Database Concurrency Exception writing Sessions #8096

• ABP Framework version: v8.3.0
• UI Type: Blazor WASM
• Database System: EF Core (PostgreSQL)
• Tiered (for MVC) or Auth Server Separated (for Angular): no
• Exception message and full stack trace: An exception was thrown by OpenIddict.Server.OpenIddictServerHandlers+Protection+CreateTokenEntry while handling the OpenIddict.Server.OpenIddictServerEvents+GenerateTokenContext event. Volo.Abp.Data.AbpDbConcurrencyException: The database operation was expected to affect 1 row(s), but actually affected 0 row(s); data may have been modified or deleted since entities were loaded.
• Steps to reproduce the issue: Unknown - appeared to happen during a token refresh while the user was using the system. Site reloaded and ended up displaying a 409 error page that appeared to be on the host-side rather than in the WASM client.

More logs are available.
