View server side error messages in anvil editor output section

What I’m trying to do:
View server side errors (eg. import errors) in the anvil editor output section. Seems the output section in the editor is only for client side output?
Am I doing something wrong or missing anything in the editor? I would like to see server side errors messages and/or stack traces to help debug issues.

What I’ve tried and what’s not working:
I have tried importing a library that does not exist yet (which is a server side error), but there is no indication of a server side error on the anvil editor when I run the app.

Code Sample:

import cloudant

Not sure if it makes a difference but I’ve since moved to the full python3 runtime, and I can see server side errors.
