We are using OpenID Connect 1.31 combined with Azure AD and XWiki 13.10.6. Nearly all works fine but we get this error message in the log file:
WARN o.x.c.o.a.i.OIDCUserManager - Failed to get user avatar from URL https://graph.microsoft.com/v1.0/me/photo/$value: IOException: Server returned HTTP response code: 401 for URL: https://graph.microsoft.com/v1.0/me/photo/$value
This happens to users with and without a microsoft user avatar.
I created a jira ticket but maybe there is some swarm intelligence in this forum to guide to the right direction.
