I've submitted a PR to add error logging to Active Job -
https://github.com/rails/rails/pull/28582.
Since it's been a couple of weeks with no comments made to the PR, I'm pointing it out here (as directed in the Contributing guide).
The original issue description is
https://github.com/rails/rails/issues/26848. In brief, the PR changes only the default logging activity of jobs that raise exceptions from logging "Performed ..." (at info level), identical to the log message for non-exceptional jobs, to "Error performing ... <exception class + message + backtrace" (at error level).
It would be nice to get this into 5.1.
Thanks,
Steve
