  hi

  You can continue to observe, If it happens occasionally, you can ignore it.

  I have refunded your ticket.

  Thanks.

  Actually it's happening a lot, and is breaking the login flow for oauth.

  Any way to ignore it for now, this is quite urgent I have been trying to hijack the AbpOpenIddictTokenStore, but I don't think the service is being replaced.

  [Dependency(ReplaceServices = true)]
  [ExposeServices(typeof(IOpenIddictTokenStore<OpenIddictTokenModel>), typeof(AbpOpenIddictTokenStore))]
  public class CustomAbpOpenIddictTokenStore : AbpOpenIddictTokenStore
  {
      private readonly HelperUtility _helperUtility;
  
      public CustomAbpOpenIddictTokenStore(
          HelperUtility helperUtility,
          IOpenIddictTokenRepository repository,
          IUnitOfWorkManager unitOfWorkManager,
          IGuidGenerator guidGenerator,
          IOpenIddictApplicationRepository applicationRepository,
          IOpenIddictAuthorizationRepository authorizationRepository,
          AbpOpenIddictIdentifierConverter identifierConverter,
          IOpenIddictDbConcurrencyExceptionHandler concurrencyExceptionHandler,
          IOptions<AbpOpenIddictStoreOptions> storeOptions)
          : base(repository, unitOfWorkManager, guidGenerator, applicationRepository, authorizationRepository, identifierConverter, concurrencyExceptionHandler, storeOptions)
      {
          _helperUtility = helperUtility;
      }
  
      public override ValueTask DeleteAsync(OpenIddictTokenModel token, CancellationToken cancellationToken)
      {
          try
          {
              return base.DeleteAsync(token, cancellationToken);
          }
          catch (AbpDbConcurrencyException)
          {
              _ = _helperUtility.SendMsgToSlack("Caught abp Token ConcurrencyException");
              return default;
          }
          catch (OpenIddictExceptions.ConcurrencyException)
          {
              _ = _helperUtility.SendMsgToSlack("Caught Token ConcurrencyException");
              return default;
          }
      }
  
      public override ValueTask UpdateAsync(OpenIddictTokenModel token, CancellationToken cancellationToken)
      {
          try
          {
              _ = _helperUtility.SendMsgToSlack("called update");
              return base.UpdateAsync(token, cancellationToken);
          }
          catch (AbpDbConcurrencyException)
          {
              _ = _helperUtility.SendMsgToSlack("Caught abp Token ConcurrencyException");
              return default;
          }
          catch (OpenIddictExceptions.ConcurrencyException)
          {
              _ = _helperUtility.SendMsgToSlack("Caught Token ConcurrencyException");
              return default;
          }
      }
  }

  Actually now that I see it I may not have overridden the methods correctly, since they are async

  So sorry, I forgot to mention that I have migrated the project to 8.2 already. and this is currently on 8.2.

  EDIT: I have updated my initial question to mention 8.2

  hi

  Does this only happen with load-balanced?

  Can you share the logs.txt of all servers?

  Based on my experience, I think only load-balanced, as it was not happening on dev, which had 1 instance, getting this on our staging side which has a minimum of 4 instances at all times. But I will confirm this now, by scaling down to 1 instance.

  Also emailing you logs at the moment.

  Feel free to use both.

  1st set of logs are from main server - 7.1.1 2nd set of logs are from identical copy of main server but on 8.2 - for test purposes, this is better, as it only has logs for the logins. and been using it for the past hour.

  Just scaled down to 1 instance, but still got the error, so not related to load balanced env.

  Set the ef core log level to Debug

  .MinimumLevel.Override("Microsoft.EntityFrameworkCore", LogEventLevel.Debug)
  

  and EnableSensitiveDataLogging

  Configure<AbpDbContextOptions>(options =>
  {
      /* The main point to change your DBMS.
       * See also BookStoreMigrationsDbContextFactory for EF Core tooling. */
      options.UseSqlServer();
      options.Configure(configureOptions =>
      {
          configureOptions.DbContextOptions.EnableSensitiveDataLogging();
      });
  });

  Ok I will try now. Give me a bit of time as I will need to connect them to redis.

  Scratch my previous comment about not related to load balanced. error was gone eventually, and then immediately came back after scaling to 4 instances.

  More information. The login flow is using OIDC from a react app, which redirects to aBP login page - > then OAUTH. which returns this

  If i immediately go to the ABP dashboard, it seems like I have a login session correctly.

  For direct dashboard login, I have to test more, but seems like login works, but logout is giving 500 errors again.

  Edit : replacing log lines with urls.

  From the logs, it seems that a web request is forwarded to multiple servers at the same time.

  Can you confirm this?

  One success and another failed.

  Isn't one a /connect/login, and the other a /connect/authorize? Time is same you are right, and I can check, but pretty sure that would defeat the purpose of a load balancer. For context its an Elastic Load Balancer on AWS (Application Load Balancer) which is supposed to round robin, and definitely not duplicate requests.

  Also can you help me override the TokenStore, that would help me temporarily. I've tried various methods but no success. I see you used it here. https://github.com/abpframework/abp/issues/15530#issuecomment-1573187239

  Thank you for your help. Is there any other way I can help you debug?

  I was kind of losing my mind on why the database wasn't working on the sample template env (already had this format in main project)

  For sensitive data logging, the code needs to be

  Configure<AbpDbContextOptions>(options =>
  {
          /* The main point to change your DBMS.
           * See also ScoobyLoginTestDbContextFactory for EF Core tooling. */
      //options.UseMySQL();
  
      options.Configure(opts =>
      {
          opts.DbContextOptions.UseMySql(configuration.GetConnectionString("Default"), ServerVersion.Parse("8.0.32-mysql"));
          opts.DbContextOptions.EnableSensitiveDataLogging();
      });
  });

  I may have narrowed down the issue with Amazon RDS proxy. was able to reproduce the issue on a new sample template, just by using RDS proxy. Will be trying main api without proxy and testing more.

  RDS proxy pools connections automatically. Is there any way to have a distributed pooling system with ABP? I have a limit for maximum database connections, and that needs to be a sum for all active instances.

  Also not sure which mechanism of it is causing this issue.

  hi

  I'm not familiar with Amazon, but the problem is basically that a request is processed twice, so there is a concurrency exception.
