System.FormatException on impersonation after upgrade to ASPNETZERO 9.0.1 #9365

9.0.1, .NET Core, Angular

When impersonating a tenant user and later switching back to host user, the following error appears in src\ProjectName.Web.Host\Startup\AuthConfigurer.cs multiple times: System.FormatException: 'The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters.'

Does any one else experience this issue!?

EDIT

Here is the content of Logs.txt:

    Hi,

    Could you check if you have this change in your source code https://github.com/aspnetzero/aspnet-zero-core/commit/007f73962dbf13cb17901fb6cb85670ea2e5d612 ?

    Thanks,

    Hi @ismcagdas!

    Yes, this file is up to date!

    I was wondering if it might be related to one of my other issues: [exception when impersonating tenant user #8611](https://support.aspnetzero.com/QA/Questions/8611/exception-when-impersonating-tenant-user). I used the #if DEBUG preprocessor directive to work around this issue in my debug environment and thought it might interfere somehow now - I then reverted my changes but it didn't solve the current problem.

    I just tried with a clean install of my project and this problem exists there as well.

    Implemented preprocessor directive as a work-around:

    #if DEBUG
            try
            {
                context.Token = SimpleStringCipher.Instance.Decrypt(qsAuthToken, AppConsts.DefaultPassPhrase);
            }
            catch
            {
                // ignore
            }
#else
            context.Token = SimpleStringCipher.Instance.Decrypt(qsAuthToken, AppConsts.DefaultPassPhrase);
#endif

    I would prefer a better solution, though ...

    PS: It seems there is a problem with the SignalR chat-service related to this as well! When impersonating a tenant user, chat-service failed to connect, also when switching back to host user, chat-service failed to connect. Since I use the workaround above the problem seems to be gone.

    Hi @alexanderpilhar

    Could you write steps to repdocue this problem on a clean project ?

    Hi @ismcagdas!

    It seems this one is another of the browser cache related problems. I cleaned all browser data and now the problem does not occur anymore!

    Thank you for your time!
