I’ve got a new problem. I have become a HTML template that I shall add for responses. It includes tables, links etc.
If I just want to send out the Template via RT it works, but as soon as I add the perl code for the transaction message, I only get out everything remaining after the perl snippet.
I have already checked the logfile, but the messages show up here doesn’t help me to track down the issue:
 [Thu Oct 29 14:37:16 2020] [error]: Invalid Template Content (Couldn’t find ===, and is not a csv/tsv template) - unable to parse: (/opt/rt5/sbin/…/lib/RT/Action/CreateTickets.pm:519)
 [Thu Oct 29 14:37:16 2020] [error]: error: unexpected end of header (/opt/rt5/sbin/…/lib/RT/Template.pm:459)
As soon as I figure out how to upload the txt file, I also provide the template used.
/edit: I uploaded it at our seafile now, I hope this helps tracking down the problem:
