Tests are not running anymore in CI
There is no issue locally. Issue is the same with c8 or nyc with and without --experimental-require-module (not needed anymore the require module has been backported in node 20.19.0 and 22.14.0)

This is an example https://github.com/nodeSolidServer/node-solid-server/tree/refs/heads/fix/issue%231798
branch fix/issue#1798

Run npm run nyc

> solid-server@5.8.5 nyc
> cross-env NODE_TLS_REJECT_UNAUTHORIZED=0 nyc --reporter=text-summary mocha --recursive test/integration/ test/unit/

(node:2062) Warning: Setting the NODE_TLS_REJECT_UNAUTHORIZED environment variable to '0' makes TLS connections and HTTPS requests insecure by disabling certificate verification.
(Use `node --trace-warnings ...` to show where the warning was created)

    triggerUncaughtException(err, true /* fromPromise */);
