The grader gave me the error below. What could the causes? Thanks!
“Sorry, your submission was incorrect. Please try again. [Errno 2] No such file or directory: ‘/shared/submission/submission.json’”
I re-submitted it and worked this time!

One theory would be “bad weather in the Cloud”. I would try again and do this sequence to minimize the size of the upload:
Kernel -> Restart and Clear Output
Save
Submit
The point is that the grader does not need to see your output: it just calls your functions.
Please give that a try and let us know what happens.
Note: I just tried submitting DLS C5 W1 A2 and A3 and it worked fine for me.
