[ERROR] Cannot submit Assignment of Week 01

I’m having trouble in submitting my programming exercises! I keep receiving this bug:

Submission Status
Go to https://www.coursera.org/learn/neural-networks-deep-learning/programming/XaIWT to see your submissions.

Please note that submitting work that isn’t your own may result in permanent failure of this course or deactivation of your Coursera account.

Bad request: {'errorCode': None, 'message': "Could not find schemas with name ''. ", 'details': None}

I have already asked at the Coursera forum months ago but I can’t solve this at all.

My guess would be that there is something corrupted about your notebook. My suggestion is to use the relevant topic on the FAQ Thread to get a fresh copy. Then carefully “copy/paste” over just your completed code.
