Steps to reproduce:

Hey there 👋I've found that any firestore call fails with TypeError: channel.createCall is not a function. Full stack trace:

Things I've tried:

• Other APIs including realtime database works fine
• Downgrading firebase-admin to 5.13.1 and 5.12.0 didn't help
• Standalone @google-cloud/firestore module has the same issue
• Downgrading grpc to 1.14.2 via yarn's resolutions didn't help

Relevant Code:

const firebase = require('firebase-admin');

firebase.initializeApp({
  credential: firebase.credential.cert('/path/to/key.json'),
  databaseURL: 'https://<PROJECT_DATABASE>.firebaseio.com/',
});

firebase.firestore().settings({
  timestampsInSnapshots: true,
});

firebase
  .firestore()
  .collection('whatever')
  .limit(1)
  .onSnapshot(snapshot => {
    snapshot.forEach(doc => {
      console.log(doc.id, '=>', doc.data());
    });
  });

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Alright, so it might've been an issue with node_modules in my monorepo. Cleaning cache and doing hard re-install fixed it. Sorry for that 😅

Cleaning cache did not help in my case. For me it happens during testing (https://firebase.google.com/docs/functions/unit-testing). Updating firebase-functions to version 2.1.0 fixed it.

Deleting and reinstalling the node_modules did it for me 🙌
