Lab 2 and 3 doesn't accept my responses

I am getting this error after submitting the response. This is really frustrating. Is there anyone who can help me with this?

This is the same “deprecation warning” that you and other students have already reported for the last couple of days.

It’s been reported to the course staff.

They are working on it. You just have to wait until they fix it.

That is the only information available.

Today I checked C2W3 and the grader worked fine for me. I will go into C2W2 and evaluate if the bug is fixed.

@Homayoun_Sohrabpour The issue seem to be solved both for C2W2 and C2W3. I have some error with C2W2 during executing bellow code in one of cells but after restart of kernel and 2nd try all went well together will grading.
