Refreshing authorization not working with expired or invalid access token about trakt.net HOT 5 CLOSED

@aspik Could you please provide the steps on how to reproduce this error? And a stack trace would be nice.

from trakt.net.

Sure:

1. start the client,
2. authorize with pin:
   https://github.com/aspik/TraktPluginMP2/blob/master/TraktPluginMP2/TraktPluginMP2/Models/TraktSetupModel.cs#L120
3. save the response to file:
   https://github.com/aspik/TraktPluginMP2/blob/master/TraktPluginMP2/TraktPluginMP2/Models/TraktSetupModel.cs#L269-L274
4. close the client,
5. start the client,
6. refresh the authorization by exchanging the refresh token:
   https://github.com/aspik/TraktPluginMP2/blob/master/TraktPluginMP2/TraktPluginMP2/Services/LibrarySynchronization.cs#L447-L464
   https://github.com/aspik/TraktPluginMP2/blob/master/TraktPluginMP2/TraktPluginMP2/Services/TraktClientProxy.cs#L58

Result: exception with message: "not authorized" is thrown.

I'm afraid that the stack trace will not be helpful. I'm using a wrapper around the TraktClient (for unit tests purpose ), and I can catch only the AggregateException:
https://github.com/aspik/TraktPluginMP2/blob/master/TraktPluginMP2/TraktPluginMP2/Services/TraktClientProxy.cs#L281-L294

@aspik I think, you didn't set the saved authorization in the client.
https://github.com/aspik/TraktPluginMP2/blob/master/TraktPluginMP2/TraktPluginMP2/Services/LibrarySynchronization.cs#L460

There might be missing this:

_traktClient.Authorization = savedAuth;

This was not needed with the old lib. And tbh I'm not sure why I have to do it? :) its only the refreshtoken which matters.
I just restored back the old check in the new version, compiled it and exchanged in my plugin. Now is all working as before :)

from trakt.net.

Ah, okay. You're right, that should also work with just the refresh token.
