Error submitting Lunar Lander assignment

Hi,

When I ran my notebook, everything ran smoothly. I passed all the tests and watched the video of the lunar lander landing smoothly. Now, when I submit the assignment, I get the following error.

Hi

My you can do just search on google “coursera lab force refresh”, a link will instruct you how to reset the notebook.

And after that you write your code again
I hope it help you
