Incompatible with firebase-functions 6.0: TypeError when starting emulator

[0xDing]

[REQUIRED] Environment info

firebase-tools: 13.16.0

Platform: macOS

[REQUIRED] Test case

// Minimal example of a Cloud Function using firebase-functions v6.0
const functions = require('firebase-functions');

exports.helloWorld = functions.https.onRequest((request, response) => {
  response.send("Hello from Firebase!");
});

[REQUIRED] Steps to reproduce

1. Install the latest version of firebase-tools
2. Create a new Firebase project and initialize Cloud Functions
3. Update firebase-functions to version 6.0 in package.json
4. Implement a simple Cloud Function as shown in the test case
5. Run firebase emulators:start

[REQUIRED] Expected behavior

The Firebase emulator should start successfully and the Cloud Function should be available for testing.

[REQUIRED] Actual behavior

The emulator fails to start, throwing the following error:

⚠  TypeError: Cannot read properties of undefined (reading 'setEmulatedAdminApp')
    at Proxy.<anonymous> (/Users/ding/.volta/tools/image/packages/firebase-tools/lib/node_modules/firebase-tools/lib/emulator/functionsEmulatorRuntime.js:363:34)

It appears that firebase-tools is not compatible with the latest firebase-functions 6.0. The error suggests that setEmulatedAdminApp is being called on an undefined object, which is likely due to changes in the structure of firebase-functions 6.0.

The issue seems to be related to the fact that setEmulatedAdminApp is specific to firebase-functions/v1, while version 6.0 defaults to v2 of Cloud Functions. For v1 functionality, it now requires a separate import from "firebase-functions/v1".

Additional context

This incompatibility is preventing developers from using the latest version of firebase-functions with the current firebase-tools. A potential workaround might be to explicitly import from "firebase-functions/v1" when using v1 features, but this doesn't solve the underlying compatibility issue with firebase-tools.

It would be greatly appreciated if the Firebase team could investigate this compatibility issue and provide guidance on how to use firebase-tools with firebase-functions 6.0, or update firebase-tools to properly support the new version structure of firebase-functions.

have the same issue migrating from v1 to v2. Downgrading firebase-functions 5.0 worked for me

I encountered the same issue with firebase-tools version 13.17.0. Like others, downgrading to firebase-functions version 5.x resolved the issue for me as well.

Hey folks, sorry to hear you encountered this issue, and thanks @0xDing for providing a detailed report! I’m able to reproduce this, let me raise this to our engineering team so they can take a look and investigate. I’ll mark this issue as reproducible.

Having this issue also, would love some resolution. I love firebase but.... the number of issues working with it are becoming insurmountable.

Downgrade to firebase-functions@5.1.1 solved the issue

Downgrading isn't really a solution, as the issue specifically comes from upgrading to v6. The goal is to resolve the problem in v6, not avoid it by reverting to an older version.
