Hi,
We have migrated to xwiki 8.2.1 in a docker environment. Everything is working
as a charm. However: When registerring a user (as an admin), I get an error.
Investigating this only gives me results that date from 2013 but nothing
recent. I am not sure how to proceed. The error is:
<error>
type Exception report
message Servlet execution threw an exception
description The server encountered an internal error that prevented it from
fulfilling this request.
exception

Is there anyone who can show the direction to look for an answer?
