Error message I don't understand

Suddenly, a few days ago when running getmail I began receiving this error message and I'm trying to figure out where it comes from and what it means.

One day it worked fine and the next not.  No changes of any kind made.

I wonder if it has anything to do with the use of xoauth2.
Like perhaps the token needing to be refreshed.
Here is my getmailrc file in case it helps.
