WebUI fails to display job details when log contains empty line #1837
Description
Bareos component version
WebUI 23.0.3~pre135.a9e3d95ca
All components are installed from the official repository for Debian 12.
Steps to reproduce
I have run a job on a laptop which came into suspend mode during backup. The job finished with a warning. When I wanted to display job details by clicking the job id, WebUI pointed me to the /job/details/509 page, but console logs did not appear. In the browser console, I saw the following error:
Uncaught TypeError: msg is undefined

After analyzing the error in the JavaScript debugger, I realized that the browser is trying to display a log message with undefined value. I am not sure, where that message came from. As a quick workaround I modified the module/Job/view/job/job/details.phtml file:
I modified line 271:
return formatLogMessage(value);
to
return formatLogMessage(value ?? "");
Now the WebUI works and displays an empty line among the log entries.
Expected results
WebUI should display job log trace.
Actual results
WebUI hangs when the log entry is undefined. I don't know where that value comes from. Maybe it is a backend problem, but still, the WebUI should handle faulty data better.
