With the following code: 

const functions = require('firebase-functions')
const admin = require('firebase-admin')
admin.initializeApp()

exports.onTest = functions.https.onRequest(async (req, res) => {
  res.json({ msg: 'done' })
})

which comes exactly from the example docs, ... running firebase emulators:start from cli generates the following error:

 ⚠  TypeError: instance.registerVersion is not a function

⚠  We were unable to load your functions code. (see above)

Several other examples on SO and other sites call #initializeApp with initializeApp(functions.config().firebase) ... but this also throws the same error.

I'm using node 8 functions and node 8 locally and basic pacakage.json dependencies:

"dependencies": {
    "firebase-admin": "^8.6.0",
    "firebase-functions": "^3.3.0"
  }

UPDATE: although the command firebase emulators:start throws the above error, the functions work in shell: 

MacPro:functions: firebase functions:shell
✔  functions: Emulator started at http://localhost:5000
>  function: apiOnSave
i  functions: Loaded functions: apiOnSave
firebase > apiOnSave()
Sent request to function.
firebase > >  function: apiOnSave

RESPONSE RECEIVED FROM FUNCTION: 200, {
  "msg": "done"
}

Doesn't anyone have suggestions on how to resolve this?

  • If have clear reproduction steps that suggest there might be a bug in the Firebase CLI, please post an issue on the Firebase CLI GitHub. https://github.com/firebase/firebase-tools – Doug Stevenson Dec 17 '19 at 17:11
  • @DougStevenson - I can't reproduce it in a freshly initialized project ... that does work. But if I copy the firebase config files and functions folder from the fresh initialized folder to the project folder, I still get the error. the same also occurs if I re-init the project folder. Are there any other config files or a cache that might be affecting why it works in a fresh folder, but not in a freshly initialized existing folder? – Tremendus Apps Dec 17 '19 at 18:10

Seems to be a bug in firebase@7.6.1. Going back to firebase@7.6.0 fixes it for me.

Direct Dependecy

Since for me, firebase is a direct dependency, this does the trick:

npm i -S firebase@7.6.0 --force

Indirect dependency

However in your case, it is an indirect dependency -- Try to find out which version your installation uses with:

npm list firebase

Try going back to a version of firebase-admin and firebase-functions that uses an earlier version of firebase.
