An exception occurred: UnpickleableExceptionWrapper: b"TaskError(b'pywikibot.Error: NoUsernameError: Failed OAuth authentication for commons

A little bit of a strange one: I started adding a few videos concurrently, the second one succeeded, but the other two gave this error:

An exception occurred: UnpickleableExceptionWrapper: b"TaskError(b'pywikibot.Error: NoUsernameError: Failed OAuth authentication for commons:commons: The authorization headers in your request are not valid: No approved grant was found for that authorization token.')"

A little strange since the token should still be good given one video worked!

(Also it let me retry, but it has to reprocess from the start again... it takes a lot of time to convert the video, but the video was already converted. It just couldn't put it on commons. I'm not sure if it's feasible but noting which commands succeeded and only retrying failed ones might be more efficient!)

I see it also on some of my uploads but don't know yet why it happens.

I haven't been able to reproduce this (locally). From reading the source code of the OAuth extension it looks like this happens if the token cannot be found in the database. The code has a retry mechanism to account for replication lag, so I'm not sure why this would happen. If it works on a retry, maybe we can workaround this by adding an automatic upload retry mechanism in V2C?

I think a retry mechanism sounds reasonable
