C1W3 - Execution of Launch Template : No file named Credentials

After grading I get an error mentioned

What is this error and how do I get around it?

Hello @Uma0697
Are you getting this error on other items too?
Can you please reboot the server on your lab and try again? You can click on the question mark on the upper menu and select Reboot.


This is the error you must get if you submit a fresh lab where you haven’t completed any parts.
