Issue with grading of C1M1 assignment

I have submitted the answers for the first assignment of the course the run the script for testing my answers which all came out correct. However, upon submitting the assignment, I am getting a score of 0/30 with the error message - “There was a problem compiling the code from your notebook, please check that you saved before submitting. Details:
No module named ‘test_your_code’”. I have run the ‘test_your_code’ code for each answer and saved the answers multiple time before submitting but I am still getting the same score.
Please let me know if anybode else is facing the same issue and how I can troubleshoot it.

Thank you!

Try restoring the notebook to the original version using the three dots in the top right corner. It’s possible that some necessary files from the lab environment were accidentally deleted.

Did you add any code that calls the “test_your_code()” function, into any of the cells that you modified?

That would cause exactly the error you’re seeing from the grader.
