QA Issue Tracker tests passed... not

Hi. I completed the FCC QA Issue Tracker project but the FCC finds something wrong with my tests:

// running tests
X All 14 functional tests are complete and passing.
// tests completed

Locally all tests are passing:

npm run test

> fcc-issue-tracker@1.0.0 test C:\Users\[cut]\Documents\Studio\JavaScript\fcc-qacert-issuetracker
> "mocha --timeout 5000 --recursive --exit --ui tdd tests/"

[...]

  14 passing (340ms)

I already tried renaming and categorizing the tests exactly as the FCC official application. Here are my code and live application. Can anyone please tell me what’s wrong?

Hold it, I found the reason: I was using a bugged version of the chai-datetime library. I had patched it locally (and pushed the patch to the official repo) but the server was still downloading the bugged npm package.
