Syntax Error not able to submit the assignment

I have a problem submitting the assignment.

I have passed all tests within the Jupyter environment, everything gives the correct outputs. However, whenever I submit the assignment, I get the following message for each of the tests:

“The notebook you provided has a syntax error that prevents it from compiling.”

I also check all cells of the correct type. Like Markdown and Code.

Can anyone help me?
