Error when `firebase deploy`ing Google Smart Home codelab action

I was trying to follow https://codelabs.developers.google.com/codelabs/smarthome-washer/#2

But I got stuck on firebase deploy on step 3.

First error:

Error: package.json in functions directory has an engines field which is unsupported. The only valid choices are: {"node": "8"} and {"node": "6"}.

After I change the package.json file to use "node":"8", then I get following error:

Error: Error occurred while parsing your function triggers.

Having trouble? Try firebase deploy --help

What do I do? Or does someone know any other resources to learn to build a google home action?

Solution

  • I was finally able to deploy when I installed the exactly mentioned dependencies in the package.json.

    I changed my package.json from -

    {
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "engines": {
    "node": ">=6.11.1"
  },
  "dependencies": {
    "actions-on-google": "^2.1.0",
    "cors": "^2.8.4",
    "firebase": "^4.0.0",
    "firebase-admin": "^5.8.1",
    "firebase-functions": "^0.8.1",
    "google-auth-library": "^0.10.0",
    "googleapis": "^27.0.0"
  },
  "private": true,
  "devDependencies": {
    "eslint": "^4.19.1",
    "eslint-config-google": "^0.9.1"
  }
}

    to -

    {
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "engines": {
    "node": ">=6.11.1"
  },
  "dependencies": {
    "actions-on-google": "2.1.0",
    "cors": "2.8.4",
    "firebase": "4.0.0",
    "firebase-admin": "5.8.1",
    "firebase-functions": "0.8.1",
    "google-auth-library": "0.10.0",
    "googleapis": "27.0.0"
  },
  "private": true,
  "devDependencies": {
    "eslint": "4.19.1",
    "eslint-config-google": "0.9.1"
  }
}

    changed all the "^2.1.0" to "2.1.0"
