[REQUIRED] Step 2: Describe your environment

• Operating System version: Linux 7u 5.3.0-24-generic firebase/firebase-admin-node#26-Ubuntu SMP Thu Nov 14 01:33:18 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

• Firebase Product: firebase-functions/firebase-admin
• Node.js version: nodejs10 runtime
• NPM version: 6.13.1

[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

Relevant Code:

I was trying to adopt https://firebase.google.com/docs/functions/config-env#automatically_populated_environment_variables. Deploying firebase function (http) with:

if (process.env.FIREBASE_CONFIG === undefined) {
    throw new Error('Missing FIREBASE_CONFIG');
}
...
admin.initializeApp(opts);

makes deployment to fail.

From terminal:

$ firebase deploy --only functions:admin.forceRcUpdate ✔ scheduler: all necessary APIs are enabled ⚠ functions[admin-forceRcUpdate(us-central1)]: Deployment error. Error setting up the execution environment for your function. Please try deploying again after a few minutes.

In logs:

Removing access to process.env.FIREBASE_CONFIG fixes the issue. Local emulator works well with it

@stari4ek To import a module just for its side effects, use this syntax: import 'firebase-functions'; https://www.typescriptlang.org/docs/handbook/modules.html#import-a-module-for-side-effects-only

[stari4ek]

did check with import 'firebase-functions'; works well.

I’m not sure if this is good practice in ts/js, but, honestly speaking, for me it looks more like implementation-specific stuff leaking outside the module during it’s import.

This issue could be closed. Thank you
