Why is admin.firestore.FieldValue undefined when running code in firebase emulator?

Question

In my firebase cloud functions, I have upgraded firebase-admin to version 11.0.0 (from 9.12.0) and engines from 12 to 16. After that admin.firestore.FieldValue is undefined when I run my code in the emulator.

When I deploy the code it works correctly.

I like to test in the emulator. Is there anything I can do to make this work in the emulator?

My code:

import * as admin from 'firebase-admin';

// Remove user permissions
await firestore.doc(`/${projectsPath}/${projectKey}`).update({
        roUids: admin.firestore.FieldValue.arrayRemove(uidOfUserToDelete),
        rwUids: admin.firestore.FieldValue.arrayRemove(uidOfUserToDelete),
});

My package.json:

{
"name": "functions",
"scripts": {
    "lint": "eslint --ext .js,.ts .",
    "build": "tsc",
    "watch": "tsc --watch",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log",
},

Can you try using `import { FieldValue } from "firebase-admin/firestore";` instead? — Dharmaraj, Jul 10 '22 at 12:16
If I try import { FieldValue } from 'firebase-admin/firestore'; I get Unable to resolve path to module 'firebase-admin/firestore' — Jørgen Rasmussen, Jul 10 '22 at 12:37

The solution is to update your import.
This worked for me:

import { FieldValue } from 'firebase-admin/firestore'

Same for TimeStamp

Instead of using

admin.firestore.FieldValue

You should import FieldValue in one of these ways:

import { FieldValue } from 'firebase-admin/firestore'

or

const { FieldValue } = require ("firebase-admin/firestore");

And then use directly FieldValue.

To fix your example:

import * as admin from 'firebase-admin';
import { FieldValue } from 'firebase-admin/firestore'

// Remove user permissions
await firestore.doc(`/${projectsPath}/${projectKey}`).update({
        roUids: FieldValue.arrayRemove(uidOfUserToDelete),
        rwUids: FieldValue.arrayRemove(uidOfUserToDelete),
});
