Re: Mail Prepare Thread error occurred in some cases when triggering the mail sending job from Scheduler Ok so the issue is that the scripts don't handle well the case when the current document doesn't have a previous revision. The problem can be reproduced with these steps: * Find a page that has only 1 revision * Edit it, then delete the new revision created * Then trigger the notif scheduler job Specifically the problem is at https://github.com/xwiki/xwiki-platform/blob/69fe80c401fc1f542bda61bd2bdf1621f881e9f6/xwiki-platform-core/xwiki-platform-web/xwiki-platform-web-templates/src/main/resources/templates/notification/email/macros.vm#L185-L190 which, in this case, results in {{$origdoc}} to be null and then the {{createDocumentDiff}} macro doesn't handle that properly and neither does {{createDocumentDiffSummary}}.
