When trying to access non-existing job like https://taskotron.fedoraproject.org/resultsdb/jobs/60908 the ResultsDB frontend fails with Err 500. Obviously, the frontend does not handle the 404 message produced by the back-end https://taskotron.fedoraproject.org/resultsdb_api/api/v1.0/jobs/60908.
Make sure the 404 err code (and the error message) are handled gracefully. Also, go through the rest of the resources (testcases, results), and make sure the not-found messages are produced in the back-end, and handled in the frontend.
