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](https://community.deeplearning.ai/t/data-engineering-week-4-capstone-1-submission-errors/885459) has not been resolved by whatever fix was done in [🛠️ Infrastructure Maintenance: Lab Availability Update](https://community.deeplearning.ai/t/infrastructure-maintenance-lab-availability-update/886346) . 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. ---

I am still not able to pass. I ran through the lab again and am still hitting 75%. Same as maielld1 above. Any way I can get money back for the past month? I should have completed this in December. ---

Thanks Jaime. I just read your full message, I missed the part about re-submitting. I did it a couple more times and got to the 80%. ---

Hi, I’m having the same issue also, it happened with no reason, there might be some issue in the grading part or the source database. Could someone please look at it urgently? ![image](https://global.discourse-cdn.com/dlai/original/3X/9/a/9a9e762b7a63840ca06936dba1be9cd81e358550.png) ---

@CheeHaw If you submit after 2hr session expired, some parts of your submission will not be graded (even if they are correct). In this case you should just try to submit again, in new session. ---

Hi Juliak, I have tried another session yesterday. Everything finished within half and hour, the result still the same. ---

I’ve been working on the Capstone Project Part 1 and have submitted several times, but my score remains stuck at 75%. The failing test cases are: - ex02: Expected 34 lines in `deftunes_transform.sessions`, but got 54 lines. - ex05: Expected 145 lines in `deftunes_transform.users`, but got 0 lines (though in my notebook I see 1,000,000 rows with 182 distinct users). Any insights would be greatly appreciated – I’m stuck and would love to finally pass this part. Thanks in advance! ![Screenshot 2026-03-16 at 7.52.26 PM](https://global.discourse-cdn.com/dlai/original/3X/8/8/88be8f6eee38b0b4d7c7257ec7717db36b888911.png) ![Screenshot 2026-03-16 at 7.52.48 PM](https://global.discourse-cdn.com/dlai/original/3X/8/8/8816804c2b46bf28fb32688eeb10abc489d32e46.png) ---
