This issue does not seem to follow the issue template. Make sure you provide all the required information.

@mirfan899 it looks like you're trying to deploy this file:
https://github.com/google/voice-builder/blob/master/cloud_functions/functions/index.js#L20

The error comes from this line:

const gcs = require('@google-cloud/storage')();

So export of the module '@google-cloud/storage' is not a function (you can see it's being invoked with ()).

It looks like that library (at least at the latest 2.x version) no longer has an import like that:
https://www.npmjs.com/package/@google-cloud/storage

Could you try changing the source const gcs = ... to const { gcs } = ... and see if that works for you?

Also I am going to close this issue since I am confident it is an issue with the "voice-builder" sample and not with the Firebase CLI but please let me know if the suggestion works for you!
