It's hard to understand the problem right no with this information. More detailed logs or debugging might be required. You're encountering a complex issue involving authorization failures, database connection problems, and potential caching issues within your application. Let's break down the problem and outline a systematic approach to debugging and resolving it.

Understanding the Problem

1. Authorization Failures:

• The logs clearly show authorization failures:
  • PermissionRequirement: Project.Project.Edit
  • PermissionRequirement: Project.Project.ScheduleEdit
• This indicates that the application is attempting to check permissions, even when requesting application configuration.
• The fact that this happens for api/abp/application-configuration which is normally available to all users is very strange.

2.Database Connection Issues:

• The logs report database connection errors:
  • An error occurred using the connection to database 'sqldb-myapp' on server 'sql-myserver.database.windows.net'.
  • System.Threading.Tasks.TaskCanceledException: A task was canceled.
• These errors suggest that the application is trying to access the database, but the connection is being canceled or failing. This is happening during the feature management store call.
• This is happening during the feature management store call which is called to check feature permissions.

3.Caching Issues:

• System.OperationCanceledException: The operation was canceled.
• at Microsoft.Extensions.Caching.StackExchangeRedis.RedisCache.GetAsync(String key, CancellationToken token)
• This indicates that a cached request to redis was cancelled. This is likely linked to the database connection issues.

4. Recurring Requests:

• The requests occur at 5-minute intervals, pointing to a potential background task or scheduled operation.

Debugging Steps

1. Identify the Source of the Recurring Requests

• Scheduled Tasks: Check your application for any scheduled tasks or background jobs that might be making these requests. Look for BackgroundJobManager, IBackgroundJob, or similar implementations.
• External Monitoring: Verify that no external monitoring tools or health checks are configured to make these requests.
• Client-Side Code: although unlikely, check any client side javascript code for any calls to the application configuration endpoint. Middleware: Check for custom middleware that might be making these calls.

2. Investigate Authorization Issues:

• Permission Configuration: Review your permission configuration (PermissionDefinitionProvider) to ensure that Project.Project.Edit and Project.Project.ScheduleEdit are correctly defined.
• Feature Checks: The stack trace indicates that FeatureChecker is involved. Investigate your feature definitions and how they are used in conjunction with permissions.
• Authentication: Ensure that your authentication setup is correct. If the application is incorrectly trying to authenticate, it might be triggering permission checks.
• Override AbpApplicationConfigurationAppService: Override the GetAuthConfigAsync method within your application's AbpApplicationConfigurationAppService to log the current user's claims and permissions. This can help you understand why authorization is failing.

3. Diagnose Database Connection Problems:

• Connection String: Double-check your database connection string for accuracy.
• Database Server Health: Monitor the health of your SQL Server instance, including CPU, memory, and disk usage. Connection Limits: Verify that you are not exceeding connection limits on your database server.
• Transient Fault Handling: Implement transient fault handling (e.g., using Polly) to retry database operations after temporary connection failures.
• EntityFramework Core Logging: Enable detailed EF Core logging to get more information about the database queries and connection attempts.

4. Analyze Caching Behavior:

• Redis Health: Check the health of your Redis server.
• Redis Configuration: Verify your Redis configuration, including connection timeouts and other settings.
• Caching Keys: Log the caching keys being used to identify any patterns or issues.
• Disable Caching Temporarily: Temporarily disable Redis caching to see if the database connection issues persist. This will help isolate the problem.

5. Environment Differences:

• Configuration: Compare the configuration files and environment variables between your local, test, and production environments. Pay close attention to database connection strings, caching settings, and feature flags.
• Infrastructure: Investigate any differences in infrastructure between your environments, such as network latency, load balancers, or firewalls.

Due to the inherent nature of the Inbox/Outbox pattern, all events are processed by a background job. When you separate your tenant's databases, that background job will not check the tenant's segregated database. To address this issue, there are two options available:

Extend/Customize the background worker to ensure it checks both databases and handles the events accordingly.

Operate two separate application instances, each working with a different database.

Hence, Point 1 (Defining a single database per tenant) is feasible with monolithic applications that do not utilize the Inbox/Outbox pattern in conjunction with BackgroundJobs.RabbitMQ.

However, Point 2 (Defining a separate database per tenant and microservice) is not achievable without intervention as outlined above. Whenever the Inbox/Outbox pattern with transaction is employed, it will not function properly with disparate databases.

See the following implementation for understanding better:

Can you make sure if AbpAuthorizationService works on your gRPC request?

Hi,

ABP doesn't provide an authentication pipeline for gRPC by default, if you make the regular ASP.NET Core authentication mechanism, ABP policies can work together. In your case it seems ASP.NET Core can't execute its own properties.

Since gRPC requests does not have header like HTTP Requests by default, you may add and resolve them manually.

Hi,

I'll ask the LeptonX team and inform you about his issue soon

Can you try adding currentSchema parameter to your connection string? https://jdbc.postgresql.org/documentation/use/#connection-parameters

I tried the same behaviour but unfortunately could not reproduce the problem. Are you sure the public schema has the tables?

Are they running on the same instance of application? Or you're using in a micro-service project?

how do we make it so that the default abp login does not appear?

You can't remove Microsoft.AspNetCore.Components.WebAssembly.Authentication package from your application because ABP modules are depending on it:

But you can remove configuration from Module class, you can find a method named ConfigureAuthentication. You can remove configuration from there and configure & register your own Oidc Client into service collection. Then you'll use your OidcClient in your own razor component/page

Hi,

Sorry for late-response, it seems you already found the problem.

Now, i need to send accessToken to the grpc endpoint because it's authorized.

ABP Framework does not implements it currently. gRPC requests are planned to be used for communication between micro-service that is not open to world and in an internal network.

But still it's an ASP.NET Core application, you can follow Microsoft's guide: https://learn.microsoft.com/en-us/aspnet/core/grpc/authn-and-authz?view=aspnetcore-9.0#authorize-users-to-access-services-and-service-methods

In the ABP Framework, Each PermissionName is a policy in the authorization logic of ASP.NET Core application, you can directly use your permissions in the [Authorize] attribute.
