Mocha not working in WebStorm in WSL due to 'unknown \"reporter\"' - node.js

Question

When running mocha in WebSstorm pointed to a WSL environment I get:
C:\Users\iursino\AppData\Local\Microsoft\WindowsApps\ubuntu.exe run "export PATH=/home/iursino/n/bin:$PATH && /home/iursino/n/bin/node --inspect-brk=49953 /mnt/c/workspace/redacted-project-name/node_modules/mocha/bin/_mocha --timeout 0 --ui bdd --reporter \"/mnt/c/Program Files/JetBrains/WebStorm 2019.2.4/plugins/NodeJS/js/mocha-intellij/lib/mochaIntellijReporter.js\" /mnt/c/workspace/redacted-project-name/src/Filename.spec.ts --grep \"^invoke lambda Expect error if lambda returns an error$\""

If I copy paste the first line into cmd though it runs. Seems to be an issue with quotes or something.
It doesn't work though, I get this:

Why is it different in cmd and WebStorm? Another question: What's up with the error I get in cmd?
Edit: uploaded the cmd output in a redacted form.
