Hi @nolafs

Welcome back to the Auth0 Community!

Thank you for posting your question. May I ask if this is a one-time event that happened or if you could reproduce this behavior?

Thank you
Dawid

Hi @nolafs

I’ve checked with the team, and this issue is probably the result of a call to an external resource, and the request is coming back with an error. Please troubleshoot with the external source to find the details of the call.

Thanks
Dawid
