Hi @aseques
a) Thank you for documenting your fix. Could you be so kind as to edit the documentation itself (requires a GitHub account and following Quickfix - Documentation) and add it there for everyone? This issue might also be relevant: 2.27.1 New data source page not working
b) It seems your account fell foul of Cannot create a Jira account to log a GeoServer/GeoTools issue - #11 by jive - could you report your Jira account issue there, so that we can try to fix it?
