Firebase functions: Can not read property https of undefined – Shopify

During firebase deploy in terminal, I get an error on this line:

// index.js in the output folder
const firebase_functions_1 = __importDefault(require("firebase-functions"));

exports.buyUsedServer = firebase_functions_1.default.https.onRequest(express);

// index.ts in the source folder
import firebaseFunctions from 'firebase-functions';

export const buyUsedServer = firebaseFunctions.https.onRequest(express);
//# sourceMappingURL=index.js.map

What is firebaseFunctions (or the default object) causing an issue here?

This is the full stack trace:

i  functions: preparing functions directory for uploading...

Error: Error occurred while parsing your function triggers.

    You should do the following:

    First import the module firebase-functions

    // The Cloud Functions for Firebase SDK to create Cloud Functions and setup triggers.
const functions = require('firebase-functions');

    Then you can call onRequest():

    exports.date = functions.https.onRequest((req, res) => {
  // ...
});

    You can check the documentation here.

    Like you, I wanted to use this ES6 import instead of CommonJS (require()). You can resolve this by using

    import { https } from 'firebase-functions';

    I got that answer from here which has a lot more information.

    TLDR: all I did was change:

    import functions from 'firebase-functions'

    To:

    import * as functions from 'firebase-functions`

    Explanation: I was using

    import functions from 'firebase-functions'

    After transpiling from TS to JS, my JS file look like this:

    const firebase_functions_1 = __importDefault(require("firebase-functions"));

    JS is trying to import the default module exported from firebase-functions. Problem is, when I looked into node_modules/firebase-functions/lib/v1/index.d.ts (this could change in the future), it does not have any default export, therefore my JS code is importing undefined:

    // node_modules/firebase-functions/lib/v1/index.d.ts
import * as logger from "../logger";
import * as analytics from "./providers/analytics";
import * as auth from "./providers/auth";
import * as database from "./providers/database";
import * as firestore from "./providers/firestore";
import * as https from "./providers/https";
import * as pubsub from "./providers/pubsub";
import * as remoteConfig from "./providers/remoteConfig";
import * as storage from "./providers/storage";
import * as tasks from "./providers/tasks";
import * as testLab from "./providers/testLab";
import { setApp as setEmulatedAdminApp } from "../common/app";
export { analytics, auth, database, firestore, https, pubsub, remoteConfig, storage, tasks, testLab, logger, };
export declare const app: {
    setEmulatedAdminApp: typeof setEmulatedAdminApp;
};
export * from "./cloud-functions";
export * from "./config";
export * from "./function-builder";
export * from "./function-configuration";

    All I did was change:

    import functions from 'firebase-functions'

    To:

    import * as functions from 'firebase-functions`

    or just import the https module:

    import { https } from 'firebase-functions'

const helloWorld = https.onCall(...)

    And you are good to go. Took me a while.
