Hi,
I'm trying to clean some issues since updating my app to ASPNET CORE 3.1 I'm getting following exception when switching to another user account (or on user impersonation) : System.Threading.Tasks.TaskCanceledException : 'A task was canceled.'
Here is the full stack trace :
System.Threading.Tasks.TaskCanceledException
HResult=0x8013153B
Message=A task was canceled.
Source=System.Private.CoreLib

I know that TaskCanceledException can occur in the logs due to SignalR. Do you know this one ? Any fix possible ?

Have a look at this one (might be the same): [exception when impersonating tenant user #8611](https://support.aspnetzero.com/QA/Questions/8611)

Hi @ricavir
Are you using latest version of ABP Nuget packages ?

@ismcagdas : yes, Abp 5.7 @alexanderpilhar : thanks, I could fix it by adding suggested code here : https://support.aspnetzero.com/QA/Questions/8611#answer-9291fbcd-73ae-e4e4-b75b-39f3b1da856d

I don't think this is the solution to the problem ... It just replaces the real
CancellationTokenProviderwith theNullCancellationTokenProvider(which does nothing). I think @maliming just wanted me to test something there.What I did as a work around to silence the exceptions during debugging is the following:
#if DEBUG try { AsyncHelper.RunSync(() => ValidateSecurityStampAsync(principal)); } catch { // ignore } #else AsyncHelper.RunSync(() => ValidateSecurityStampAsync(principal)); #endif -

You are right, I just replaced it by a try/catch block to avoid logging these exceptions.
