Translate error codes in Discover instead of telling me "Report generated error (321)"

Occasioanly I get error codes in Discover. It should be easy enough to have a lookup table translate the error code into an easy-to-understand error message. I am applying a segment filter to a report and goth the error message "Report generated error (103)" then I tweaked the rpeort and got the message "Report generated error (321)". It would be much better if I could just read the eror message and have it explain - in plain English - what is wrong.
