I just ran into this same problem myself and solved it by installing and importing the @firebase/functions npm package. I found the solution on github here: https://github.com/firebase/firebase-js-sdk/blob/master/packages/functions/README.md

From the README on github:

ES Modules

import firebase from '@firebase/app';
import '@firebase/functions'
// Do stuff w/ `firebase` and `firebase.functions`

CommonJS Modules

const firebase = require('@firebase/app').default;
require('@firebase/functions');

// Do stuff with `firebase` and `firebase.functions`

Hope that helps! The actual documentation is not very clear about having to do this in order to call the functions.
