Error submitting programming assignment

Here’s the error:

Tried refreshing, did not help.

This seems to be some sort of intermittent problem with the Coursera grader backend platform. There have been several reports of this error over the last few days, but the problem seems to be temporary. Here’s another recent thread about it. And here’s another.

Hi @dzenilee,

I came across the same last night. As Paul mentioned, it is temporary, and it was working again after a few minutes. Hopefully, it’ll be working again when you try next.
