App activate after Update: getUserInfoFromToken() must be of the type string, null given


after an update i have the following error:

I had to disable the app, because i ran into an 500 error, afterwards, when activating:

Have you tried logging out and logging back in?

Also are you using any user_backend like LDAP, SAML or social login?

I have tried logging out and logging back in.
With the update from 19 to 20.0.1 it stopped working, i hoped the updates 20.0.1, 2, 3 make it wok again.

No, only second factor.

You can check if the update 2020.12.1 fixes the issue.
