Good night! Mine is Wilson Palmeira, I am enrolled in the Course M220JS.
When I run npm test -t projection, it fails, below is the error message. How to fix it?
C:\mflix-js>npm test -t projection
server@1.0.0 test C:\mflix-js
jest --passWithNoTests “projection”

Jest did not exit one second after the test run has completed.
This usually means that there are asynchronous operations that weren’t stopped in your tests. Consider running Jest with --detectOpenHandles to troubleshoot this issue.
