Make bundle failing with: Hidden import 'tutorlts.__about__' not found'

Hi Everyone,
I was trying to setup tutor development environment for open edX, following these guidelines: Tutor development — Tutor documentation
It is breaking 2 testcases, I commented them out but now “make bundle” is failing with " Hidden import ‘tutorlts.about’ not found’ ".
Need help.

Please describe the exact commands that you executed. Paste here the full error log. Indicate which test cases were failing.
