Hello @Mohsan_Iqbal,

I think you may find this topic interesting. It is about the same error and I hope it can help you!

Cheers,

Then how you submit because there is no option of submit assignment in new notebook?

I think then you can copy the name of your original notebook to somewhere, rename the original notebook to something else, then rename your new notebook to the name you have copied. Open the assignment from coursera again, and then you should see the submit button.

Ok i will try again. Thanks

What is the problem now?
