NotAuthenticated: Authentication credentials were not provided.

[sentry-io]

Seeing a lot more of this exception, but I'm not sure it's meaningful.

• take a look at the issue in Sentry and see if there's an actual bug to be fixed. Or is it just an unauthenticated request?
• if not, take some action to stop raising this error to Sentry
