Scrubber.pm error on ticket display

Hi there,

I’m running into an issue with my RT 5.0 installation. If I tail my syslog, RT is reporting the following error when I go to the ticket display page (Ticket/Display.html):

Sep 15 16:50:03 tickets RT: [1116] Use of uninitialized value in pattern match (m//) at /usr/local/share/perl/5.28.1/HTML/Scrubber.pm line 223.

The page appears to load correctly but this error repeats in my syslog several times each time a ticket is viewed. Any ideas?

I’m running RT 5.0 on Debian 10. Please let me know if any other information is necessary. I appreciate any and all help and advice. Thanks!
