Course 5 Week 4, C5W4 UNQ_C8, 87/100

Course Q&A Deep Learning Specialization Sequence Models

Hello, I have successfully passed all the tests during the exercise of the course 5 week 4, but I have only 87/100 after I have submitted my assignment.
Could you please help me with that?
That’s the grader output:

Code Cell UNQ_C8: Unexpected error (ValueError(“Attempt to convert a value (None) with an unsupported type (<class ‘NoneType’>) to a Tensor.”)) occurred during function check. We expected function Transformer to return type <class ‘tuple’>. Please check that this function is defined properly.
If you see many functions being marked as incorrect, try to trace back your steps & identify if there is an incorrect function that is being used in other steps.
This dependency may be the cause of the errors.

The problem has been solved after I resent the assignment again.

What was the error? I’m running in to the same issue.

Edit: Never mind, I resubmitted as well and it came out correct.

I am having the same issue, and I have resubmitted 3 times but no change.
