Legacy compat API of firebase-admin 11.x breaks Cloud Functions for Firebase

[READ] Step 1: Are you in the right place?

I think so, yes.

[REQUIRED] Step 2: Describe your environment

See my previous report on Firebase Functions for details about my environment. Since then, I have updated my TS version to 4.6.4, which fixed the errors I initially had with Admin SDK. But now I have a fresh set of errors.

• Operating System version: GH Actions image + macOS Monterey 12.5.1
• Firebase Product: database, functions
• Firebase SDK version: 11 (see more)
• Node.js version: 16 (see more)
• NPM version: 8 (see more)

The problem I’m reporting started happening after I updated Admin from 10.3.0 to 11.2.0.

[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

It looks like initialization of Firebase Admin fails on launch. This happens both with serve and deploy --only functions. TSC and Lint pass fine without any issues.

Here’s the console output with --debug:

Relevant Code:

This is how I initialize the SDK now:

import * as functions from "firebase-functions";
import * as firebaseAdmin from "firebase-admin";

firebaseAdmin.initializeApp();

...

In another file I also have the following, but I don’t think my run ever reaches that stage to require the file to run.

import * as firebaseAdmin from "firebase-admin";

private static database = firebaseAdmin.database();

...

What have I tried:

• Googling, StackOverflowing, etc.
• This advice, even though the official documentation does not reflect it. It doesn’t fix the issue for me
• Reverting back to v10, which works but is not a solution to this problem

Priority

From my POV it’s high priority because the functions won’t launch, but not urgent. I can give more code/information if needed.

Verified, the bug is gone if I simply downgrade axios to v0.27.2.

@milosmns Thanks for sharing your updates! Looks like we can close the issue for now - I’ll reach out to admin sdk to see if breaking const { initializeApp } = require("firebase-admin") was intentional in v11.
