TS compile errors in newly initialised Firebase Functions project

[maks]

I followed the instructions here to initialise my local dev environment to build Firebase Cloud Functions for use with Typescript.

I created this slightly modified example index.ts:

// The Cloud Functions for Firebase SDK to create Cloud Functions and set up triggers.
import * as functions from "firebase-functions";

// The Firebase Admin SDK to access Firestore.
import * as admin from "firebase-admin";


export const helloWorld = functions.https.onRequest(async (request, response) => {
  functions.logger.info("Hello logs!", {structuredData: true});

  // Push the new message into Firestore using the Firebase Admin SDK.
  const writeResult = await admin.firestore().collection('messages').add({m: "hi from test function"});

  response.send(`Message with ID: ${writeResult.id} added.`);
});

As per the instructions I then ran: npm run build
but instead of successful compilation I get:

> build
> tsc

For me it has fixed the issue, thank you for acting on it so quickly! 🎉

I simply updated my firebase cli (just in case) and then did: npm upgrade and checking in my package-lock.json I can see:

"node_modules/google-gax": {
      "version": "2.30.3",
...

and now npm run build runs without errors.
