Emojify_V2 rating

All compiled without errors and all tests passed, but i get 0 points in grading.
The error is in Exercise 5:
Cell #14. Can’t compile the student’s code. Error: ValueError('operands could not be broadcast together with shapes (5,2) (5,) ',)

I restarted the kernel and run all cells again. No error there.

Can you give me an advise how to solve?
