models.Owner.DoesNotExist: Owner matching query does not exist.

Inizia da app/codecov_auth/views/github.py e app/codecov_auth/views/base.py per seguire il callback fino alla creazione dell’owner, quindi leggi app/codecov_auth/signals.py e app/utils/shelter.py, dove il traceback arriva all’inizializzazione del client Pub/Sub. Riproduci il callback di GitHub con la configurazione locale documentata e verifica che non restituisca più un 500 quando le credenziali richieste sono disponibili.

When login with github callback, I got a error:

{"error": "Server Error (500)"}

In api container, it raises an error:

  "message": "Internal Server Error: /login/github",

The exc_info details:

How can I fix this ?
