I have completed the Regulation Assignment, my code has passed all tests, but when submitting the assignment for grading, the waiting time is very long, and I received a score of 0.
There is some technical issue. The best we can do is to wait for Coursera staff to fix it.
oh, i got it, Thank Mentor @saifkhanengr
A few students reported the issue has been resolved. Try submitting your assignment again…
