Finally passed Week 4 Capstone 1, but the fundamental problem (54 vs 34 lines) has NOT been fixed

I finally got an 80/100 in the Capstone 1 autograder. I think this is the highest grade you can achieve because the error:

Failed test case: Incorrect output in ‘ex02’: Number of lines do not match.
Expected:
34 lines,
but got:
54 lines.

… under “dev.deftunes_transform tables output” from Data Engineering Week 4 Capstone 1 Submission Errors has not been resolved by whatever fix was done in 🛠️ Infrastructure Maintenance: Lab Availability Update .

The issue is that occasionally, one of the other autograding function fails with ““There was a problem loading the file ‘credentials’. Details: [Errno 2] No such file or directory: ‘/shared/submission/credentials’” seemingly randomly. If you “Submit Assignment” often enough, “dev.deftunes_transform tables output” will always fail, but you might get lucky and not run into the other ‘No such file or directory’ error above from the fickle autograder.

Hope deeplearning.ai fixes this at some point. But for anyone who is still stuck, just persistently submit if you think your Capstone 1 is complete and executed perfectly. I had to re-submit about 6 times before I finally got an 80/100 (the minimum passing grade).

And I was able to pass without Rebooting or Restarting the lab. Neither Qwiklabs nor Coursera Support could restart the lab for me despite numerous attempts and suggestions.
