The error occurred right after granting permissions from my Google account. The permissions were granted but I could never access your application page. I just tried again, now I got an "Error handling OAuth callback" after granting permissions. Signing in again does not work either. (I did remove all of the app's permissions in my Google security settings before, so to Google it looked like the application was requesting all of its permissions again.)

I do see it in the logs now. So weird, as dozens of people successfully signed up without this issue. Have added more logs now again to double down on that specific area where this issue is caused. Maybe another login attempt now will be able to uncover the gap.

Thanks for removing the permissions in Google, as that's also key in this debugging.

Mind if I send you an email to debug further there?

Quick shoutout to slhck for helping me debug and resolve this issue. Thank you!

tl;dr: Ran into issues because the DB was expecting a profile picture URL from Google auth (string) or NULL, but JavaScript being JavaScript tried to insert "undefined".
