Post mortem log file cannot be accessed

• Start a clean environment
• Run
  ecl run hthor textsearch1.ecl --server=<ip:port>
  in testing/regress/ecl.
• Look at the workunit page, select helpers

There is an entry on the end post-mortem. If you click on it then you get some java script displayed. If you select it and click file it magically opens a new tab.

The file did exist on disk, and was referenced by the work unit:

"/var/lib/HPCCSystems/debug/hthor-w20220404-090842-6jvk2/2022-04-04T09:08:48+00:00"
