Target Deploy for Firebase Functions

Question

I'm trying to set a target deploy for Firebase Functions. https://firebase.google.com/docs/cli/targets

This is the firebase.json file

{
  "functions": [{
    "target": "production",
    "source": "src/prod/functions",
    "predeploy": [
      "npm --prefix \"$RESOURCE_DIR\" run lint",
      "npm --prefix \"$RESOURCE_DIR\" run build"
    ]
  }]
}

The predeploy runs normally but when deploying gets an error

functions[prod]: Finished running predeploy script.
Error: An unexpected error has occurred.

If I go to firebase-debug.log it shows:

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type undefined

Putting the Functions folder on the project root it will deploy normally.

What is missing here?

The documentation states that "Firebase supports deploy targets for: Firebase Hosting sites, Cloud Storage for Firebase storage buckets, Firebase Realtime Database instances" — Renaud Tarnec

Try running firebase init and set the options as best you can so it doesn't overwrite your existing project. I had to run it from the parent directory of /functions otherwise it will create a new directory but maybe there is some option to set a different directory name to suit your case.
