I had passed all the test cases, but getting this error when I tried to submit it. Can someone help me with this
Did you by any chance changed the name of the notebook?
I think @Juan_Olano is right.
Please consider @Juan_Olano’s advice. or rename your notebook and reset the lab by adding
"?forceRefresh=true” to the end of your Lab URL.
@uvaisMN, please let me know if you still face issues.
This is an intermittent error in the Coursera grader infrastructure that we’ve been seeing over the last couple of weeks. Here’s a recent thread about it.
Hey, I didn’t change the notebook name. As @paulinpaloalto mentioned I believe it is caused because of some intermittent error in the Coursera backend. Now I tried submitting it again and it worked. Thank you all for the assistance.
