    No configuration found for Microsoft.EntityFrameworkCore.DbContext, Microsoft.EntityFrameworkCore, Version=7.0.1.0, Culture=neutral, PublicKeyToken=adb9793829ddae60! Use services.Configure<AbpDbContextOptions>(...) to configure it.

    You are installing the chat module to product service, right? You can try:

    public class ProductServiceDbContext : AbpDbContext<ProductServiceDbContext>, IChatDbContext
....


context.Services.AddAbpDbContext<ProductServiceDbContext>(options =>
{
    options.ReplaceDbContext<IChatDbContext>();
    options.AddDefaultRepositories(includeAllEntities: true);
});

    Hi,

    You need to configure the SignalR URL.

    For example:

    Configure<ChatBlazorWebAssemblyOptions>(options =>
{
    options.SignalrUrl = builder.Configuration["RemoteServices:Chat:BaseUrl"];
});

    Hi,

    You should write this in the Blazor app.

    and should i update anything in app settings of Product service?

    No, you don't.

    Could not find VoloChatAvatarManager.createCanvasForUser

    You can try running the abp bundle command in the Blazor app folder.

    Hi,

    It's just an example; you should replace the builder.Configuration["RemoteServices:Chat:BaseUrl"]; with the real URL.

    Gateway URL or Product service URL.

    Update the gateway config file:

    "DownstreamPathTemplate": "/signalr-hubs/{everything}",
    "DownstreamScheme": "wss",
    "DownstreamHostAndPorts": [

    Sorry, I am missing a verb.

    You can remove the UpstreamHttpMethod to allow any verbs:

    {
    "ServiceKey": "Signalr Service",
    "DownstreamPathTemplate": "/signalr-hubs/{everything}",
    "DownstreamScheme": "wss",
    "DownstreamHostAndPorts": [

    Hi,

    Steps:

    • Update the appsettings.json
      "RemoteServices": {
    "AbpIdentity": {
      "BaseUrl": "https://localhost:44388/",
      "UseCurrentAccessToken": "false"
    }
  },
  "IdentityClients": {
    "Default": {
      "GrantType": "client_credentials",
      "ClientId": "AdministrationService",
      "ClientSecret": "1q2w3e*",
      "Authority": "https://localhost:44322",
      "Scope": "IdentityService",
      "RequireHttps": "true",
      "ValidateIssuerName": "true",
      "ValidateEndpoints ": "true"
    }
  },
    • Grant user lookup permission to AdministrationService

    You can create an application named ProductService instead of using AdministrationService

    • Add package references

    <PackageReference Include="Volo.Abp.Identity.Pro.HttpApi.Client" Version="7.2.2" /> <PackageReference Include="Volo.Abp.Http.Client.IdentityModel.Web" Version="7.2.2" />

    [DependsOn(typeof(AbpHttpClientIdentityModelWebModule))]
[DependsOn(typeof(AbpIdentityHttpApiClientModule))]
public class ProductServiceHttpApiHostModule : AbpModule
    • Update ProductServiceHttpApiHostModule
    public override void OnApplicationInitialization(ApplicationInitializationContext context)
{
    var app = context.GetApplicationBuilder();
    var env = context.GetEnvironment();

    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }

    app.Use(async (httpContext, next) =>
    {
        var accessToken = httpContext.Request.Query["access_token"];

        var path = httpContext.Request.Path;
        if (!string.IsNullOrEmpty(accessToken) &&
            (path.StartsWithSegments("/signalr-hubs/chat")))
        {
            httpContext.Request.Headers["Authorization"] = "Bearer " + accessToken;
        }

        await next();
    });
    
    ........
}

    Hi,

    Now Application loading and chat working.

    but may i know why we should use web reference in host module?

    <PackageReference Include="Volo.Abp.Http.Client.IdentityModel.Web" Version="7.2.2" />

    since my project is Blazor web assembly.

    Hi,

    Because the product service needs to load user information from the identity service and the package was added to ProductService.HttpAPI.Host not the Blazor app.
