I've already done all the NPM installs, but no way...
A few hours ago it worked and recently stop working. My partner is running the same code and it works for him.
I tryed try deleting first both the 'package-lock.json' file and the 'node_modules' folder before running the npm install command again but don´t work.

Do anyone know where is the problem?

Thank you

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

I am facing the same issue still. Inspite of doing npm-install , on npm start, firebase-admin cannot be found.
