Root cause
Fix: force the correct content type on the action and let Swagger describe it properly
Example:
using Microsoft.AspNetCore.Mvc;
using Volo.Abp.Content;
public class CreateFileInputWithStream
{
public string Name { get; set; }
public IRemoteStreamContent File { get; set; }
public ExtraPropertyDictionary ExtraProperties { get; set; }
}
[ApiController]
[Route("api/app/organization-attachment")]
public class OrganizationAttachmentController : ControllerBase
{
[HttpPost]
[Consumes("multipart/form-data")]
public async Task<AttachmentDto> CreateAsync(
[FromQuery] Guid attachmentTypeId,
[FromQuery] Guid entityId,
[FromForm] CreateFileInputWithStream inputWithStream,
[FromQuery] bool replaceByAttachmentType = false,
[FromQuery] bool autoSave = false)
{
// call your service method here
// return await _appService.CreateAsync(...);
throw new NotImplementedException();
}
}
Notes:
[Consumes("multipart/form-data")]
public virtual Task<TAttachmentDto> CreateAsync(
Guid attachmentTypeId,
TEntityKey entityId,
[FromForm] CreateFileInputWithStream inputWithStream,
bool replaceByAttachmentType = false,
bool autoSave = false)
{ ... }
After adding Consumes + FromForm, re-run and check the Blazor Server Swagger. It should now show a multipart/form-data body with a binary File field, matching your HttpApi.Host/API swagger.
Ensure the WASM static proxy posts FormData
// In Blazor WASM
var form = new MultipartFormDataContent();
form.Add(new StringContent(attachmentTypeId.ToString()), "attachmentTypeId");
form.Add(new StringContent(entityId.ToString()), "entityId");
form.Add(new StringContent(input.Name), "inputWithStream.Name");
form.Add(new StreamContent(fileStream) { Headers = { ContentType = new MediaTypeHeaderValue(fileContentType) }}, "inputWithStream.File", fileName);
// plus ExtraProperties if needed
Prefer using the generated C# static proxy method for the service interface; once Swagger describes multipart/form-data correctly, the proxy will send the right content type and 415 will disappear.
If the Blazor Server host still shows the wrong content type

The Docs module reads only ElasticSearch:Url from IConfiguration in DefaultElasticClientProvider. To use credentials, extend DocsElasticSearchOptions.Authenticate to apply BasicAuthentication (or your desired auth) to the Elastic client settings, and bind username/password from configuration.
Add these to appsettings.json: { "ElasticSearch": { "Url": "https://elasticsearch-sample-es-http.elastic-system.svc.cluster.local:9200", "UserName": "myuser", "Password": "mypassword" } }
Create a custom IElasticClientProvider and replace the default one: using Microsoft.Extensions.Configuration; using Microsoft.Extensions.DependencyInjection; using Microsoft.Extensions.Options; using Nest; using System; using Volo.Abp.DependencyInjection; using Volo.Docs.Documents.FullSearch.Elastic;
public class BasicAuthElasticClientProvider : IElasticClientProvider, ISingletonDependency { private readonly DocsElasticSearchOptions _options; private readonly IConfiguration _configuration;
public BasicAuthElasticClientProvider(IOptions<DocsElasticSearchOptions> options, IConfiguration configuration)
{
_options = options.Value;
_configuration = configuration;
}
public IElasticClient GetClient()
{
var node = new Uri(_configuration["ElasticSearch:Url"]);
var settings = new ConnectionSettings(node)
.DefaultIndex(_options.IndexName);
// Apply Basic authentication using configuration
var username = _configuration["ElasticSearch:UserName"];
var password = _configuration["ElasticSearch:Password"];
if (!string.IsNullOrWhiteSpace(username) && !string.IsNullOrWhiteSpace(password))
{
settings = settings.BasicAuthentication(username, password);
}
// If you already use Options.Authenticate, keep it to allow further customization
return new ElasticClient(_options.Authenticate(settings));
}
}
Register your replacement in your module: using Microsoft.Extensions.DependencyInjection; using Volo.Abp.Modularity; using Volo.Docs.Documents.FullSearch.Elastic;
[DependsOn(typeof(VoloDocsDomainModule))] public class YourModule : AbpModule { public override void ConfigureServices(ServiceConfigurationContext context) { context.Services.AddSingleton<IElasticClientProvider, BasicAuthElasticClientProvider>(); } }

Current behavior (ABP v9.3.3): Volo.Abp.AzureServiceBus’s ConnectionPool expects a connection string and throws when it’s missing. This prevents using Managed Identity out-of-the-box.
Workable approach today (non-breaking, recommended):
Example:
using Azure.Core;
using Azure.Identity;
using Azure.Messaging.ServiceBus;
using Microsoft.Extensions.Options;
using Volo.Abp;
using Volo.Abp.AzureServiceBus;
using Volo.Abp.Modularity;
[DependsOn(typeof(AbpAzureServiceBusModule))]
public class MyAzureServiceBusMiModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
// Configure your namespace in options
Configure<AbpAzureServiceBusOptions>(opt =>
{
opt.Namespace = "<your-namespace>"; // e.g. mybusns
// You can still set TopicName/SubscriptionName if you use ABP’s distributed event bus
});
context.Services.AddSingleton<TokenCredential, DefaultAzureCredential>();
// Replace ServiceBusClient registration to use MI instead of connection string
context.Services.AddSingleton<ServiceBusClient>(sp =>
{
var options = sp.GetRequiredService<IOptions<AbpAzureServiceBusOptions>>().Value;
var credential = sp.GetRequiredService<TokenCredential>();
// Fully qualified namespace: "<namespace>.servicebus.windows.net"
var fqn = $"{options.Namespace}.servicebus.windows.net";
return new ServiceBusClient(fqn, credential);
});
// Optionally: if you use sender/processor factories relying on ConnectionPool,
// you can replace IConnectionPool with your own implementation.
context.Services.Replace(ServiceDescriptor.Singleton<IConnectionPool, ManagedIdentityConnectionPool>());
}
}
// Example minimal pool that creates clients using MI when no connection string is present
public class ManagedIdentityConnectionPool : IConnectionPool
{
private readonly ConcurrentDictionary<string, ServiceBusClient> _clients = new();
private readonly TokenCredential _credential;
public ManagedIdentityConnectionPool(TokenCredential credential)
{
_credential = credential;
}
public ServiceBusClient Get(string fullyQualifiedNamespace, string? connectionString = null)
{
// Prefer connection string when provided, otherwise use MI
return _clients.GetOrAdd(fullyQualifiedNamespace, ns =>
{
if (!string.IsNullOrWhiteSpace(connectionString))
{
return new ServiceBusClient(connectionString);
}
return new ServiceBusClient(ns, _credential);
});
}
}
Notes:
Ensure the managed identity (system-assigned or user-assigned) has at least Azure Service Bus Data Sender/Receiver roles on the namespace.
For ABP Distributed Event Bus, keep using AbpAzureServiceBusOptions for entity names (topic/subscription). Only authentication changes.

Recommended approach for ABP v8.x AuthServer (OpenIddict-based):
Example: Razor Pages filter registered in AuthServer
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.Filters;
using Microsoft.AspNetCore.WebUtilities;
using System.Web;
using Volo.Abp.OpenIddict.Applications;
using Volo.Abp.DependencyInjection;
public class EnforceReturnUrlFilter : IAsyncPageFilter, ITransientDependency
{
private readonly IOpenIddictApplicationRepository _appRepo;
public EnforceReturnUrlFilter(IOpenIddictApplicationRepository appRepo)
{
_appRepo = appRepo;
}
public Task OnPageHandlerSelectionAsync(PageHandlerSelectedContext context) => Task.CompletedTask;
public async Task OnPageHandlerExecutionAsync(PageHandlerExecutingContext context, PageHandlerExecutionDelegate next)
{
var http = context.HttpContext;
var path = http.Request.Path.Value?.ToLowerInvariant() ?? string.Empty;
// Pages we want to restrict when unauthenticated:
var isAccountEntry = path.Equals("/account/login", StringComparison.OrdinalIgnoreCase)
|| path.Equals("/account/register", StringComparison.OrdinalIgnoreCase)
|| path.Equals("/account/forgotpassword", StringComparison.OrdinalIgnoreCase)
|| path.Equals("/account", StringComparison.OrdinalIgnoreCase)
|| path.Equals("/", StringComparison.OrdinalIgnoreCase);
if (isAccountEntry && !http.User.Identity?.IsAuthenticated == true)
{
var returnUrl = http.Request.Query["returnUrl"].ToString();
// Require a returnUrl
if (string.IsNullOrWhiteSpace(returnUrl))
{
context.Result = new ForbidResult(); // triggers challenge in most setups; you can also Redirect to a safe page
return;
}
// Validate that returnUrl ultimately maps to a registered client redirect URI
// Typical returnUrl on login is '/connect/authorize?...redirect_uri=...'
var absoluteReturn = returnUrl.StartsWith("/", StringComparison.Ordinal) ? $"{http.Request.Scheme}://{http.Request.Host}{returnUrl}" : returnUrl;
var uri = new Uri(absoluteReturn, UriKind.Absolute);
var query = QueryHelpers.ParseQuery(uri.Query);
if (!query.TryGetValue("client_id", out var clientId) ||
!query.TryGetValue("redirect_uri", out var redirectUri))
{
context.Result = new ForbidResult();
return;
}
var app = await _appRepo.FindByClientIdAsync(clientId!);
if (app == null || app.RedirectUris == null || !app.RedirectUris.Contains(redirectUri!))
{
context.Result = new ForbidResult();
return;
}
}
await next();
}
}
Register the filter in your AuthServer Web module:
using Microsoft.AspNetCore.Mvc.RazorPages;
using Volo.Abp.Modularity;
public class AuthServerWebModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
Configure<RazorPagesOptions>(options =>
{
// Authorize everything by default
options.Conventions.AuthorizeFolder("/");
// Allow anonymous access to Account pages because they must be reachable for the OIDC flow,
// but guarded by our EnforceReturnUrlFilter.
options.Conventions.AllowAnonymousToFolder("/Account");
options.Conventions.AllowAnonymousToPage("/Error");
// Add our enforcement filter globally
options.Conventions.AddFolderApplicationModelConvention("/",
model => model.Filters.Add(new ServiceFilterAttribute(typeof(EnforceReturnUrlFilter))));
});
}
}

Add this to your Web module’s ConfigureServices:
using Microsoft.AspNetCore.Mvc.RazorPages;
using Volo.Abp.Modularity;
[DependsOn(typeof(AbpAspNetCoreMvcUiThemeSharedModule))] // typical Web module deps
public class YourProjectWebModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
Configure<RazorPagesOptions>(options =>
{
// Option A: Authorize only the index page
options.Conventions.AuthorizePage("/Index");
// Option B (broader): Authorize the entire site, then allow anonymous only for account pages you need
// options.Conventions.AuthorizeFolder("/");
// options.Conventions.AllowAnonymousToAreaPage("Account", "/Login");
// options.Conventions.AllowAnonymousToAreaPage("Account", "/Register");
// options.Conventions.AllowAnonymousToAreaPage("Account", "/ForgotPassword");
// options.Conventions.AllowAnonymousToAreaPage("Account", "/ResetPassword");
// options.Conventions.AllowAnonymousToAreaPage("Account", "/EmailConfirmation");
// options.Conventions.AllowAnonymousToAreaPage("Account", "/TwoFactor");
// options.Conventions.AllowAnonymousToPage("/Error");

Fix it by aligning the API resources/audiences:
Ensure the Hangfire client requests an API scope that maps to a resource with a known audience.
Recommended OIDC client options for Hangfire MVC:
services.AddAuthentication()
.AddCookie()
.AddOpenIdConnect(OpenIdConnectDefaults.AuthenticationScheme, options =>
{
options.Authority = configuration["AuthServer:Authority"];
options.RequireHttpsMetadata = true; // behind ingress, ensure ForwardedHeaders or force https if needed
options.ClientId = configuration["AuthServer:HangfireClientId"];
options.ClientSecret = configuration["AuthServer:HangfireClientSecret"];
options.ResponseType = OpenIdConnectResponseType.Code;
options.UsePkce = true;
options.SaveTokens = true;
// If you DON’T need /userinfo, disable it to avoid the "valid audience" check there:
options.GetClaimsFromUserInfoEndpoint = false;
// Otherwise, keep it true and request a scope that maps to a resource with accepted audience:
// options.GetClaimsFromUserInfoEndpoint = true;
options.Scope.Clear();
options.Scope.Add("openid");
options.Scope.Add("profile");
options.Scope.Add("email");
options.Scope.Add("phone");
options.Scope.Add("offline_access");
options.Scope.Add("HangfireService"); // must be a registered API scope/resource
options.SignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
});
Register the API resource/scope on AuthServer properly:

In Kubernetes, the browser reaches the Hangfire Dashboard via the public host (ingress), but your Hangfire app is sending an internal host (treva-hangfire) in the OIDC request. OpenIddict requires an exact string match.
Apply all steps below:
Fix the redirect_uri to use the public HTTPS host of the Hangfire Dashboard
Register the exact public callback(s) on the Hangfire client in AuthServer
Keep HTTPS everywhere
Seed the Hangfire OpenIddict client with the correct URIs Example (adjust hosts to your real public domains):
await CreateOrUpdateApplicationAsync(
name: "Hangfire",
type: OpenIddictConstants.ClientTypes.Confidential,
consentType: OpenIddictConstants.ConsentTypes.Implicit,
displayName: "Hangfire Client",
secret: "1q2w3e*",
grantTypes:
[
OpenIddictConstants.GrantTypes.AuthorizationCode,
OpenIddictConstants.GrantTypes.ClientCredentials,
OpenIddictConstants.GrantTypes.RefreshToken,
"pushed_authorization"
],
scopes:
[
OpenIddictConstants.Scopes.OpenId,
OpenIddictConstants.Scopes.Profile,
OpenIddictConstants.Scopes.Email,
OpenIddictConstants.Scopes.Phone,
OpenIddictConstants.Scopes.OfflineAccess,
"roles",
"HangfireService"
],
redirectUris:
[
"https://treva-hangfire.tav.aero/signin-oidc"
],
postLogoutRedirectUris:
[
"https://treva-hangfire.tav.aero/signout-callback-oidc"
]
);
Notes:
For a server-side MVC client, Authorization Code (+ optional PKCE) with Refresh Token is sufficient. You typically don’t need Implicit or Password grants.
PAR is fine; it still requires the redirect_uri to match exactly.
Clear caches and restart AuthServer
Verify the actual value sent
