Firebase - TypeError: Path must be a string. Received undefined

Question

I am just starting up with firebase.

i am not sure ins and out of the firebase and based on my vaguely understanding, I have configured my app this way.

In the main Index.js file, I am requiring

const path = require('path')
const firebaseConfig = require("./src/config/firebaseConfig.js")
const firebaseDb = require("./src/helperFunctions/firebase_db.js")

Here, firebaseConfig is the place where I am configuring my firebase

const firebaseConfigJSON = require("./functions-config.json")
const admin = require("firebase-admin");


admin.initializeApp({
    credential: admin.credential.cert(firebaseConfigJSON),
    databaseURL: "https://functions-firebase-43a59.firebaseio.com"
})

const db =  admin.firestore()
db.settings({ timestampsInSnapshots: true });

 module.exports = {
    db
 }

and then using this imported Db in firebaseDb

//All the operations at firebase store would be done from here 
const firebaseDb = require("./../config/firebaseConfig.js")

    firebaseDb.db.collection('users').add({
        name: "Rohit Bhatia",
        age: "24"
    })
    .then((response) => {
        console.log("this is response", response)
    })
    .catch((err) => {
        console.log("This is error in firebase", err)
    })

Since most of the code is singleton here, I was expecting everything to go smoothly until I received following error

This is error in firebase TypeError: Path must be a string. Received undefined

Can someone please help me in figuring out what could I be doing wrong? or perhaps did I actually got the firebase?

My initial goal was to create a collection in my firebase via my express app before putting data from api routes.

Answer 1

Try running: npm install [email protected]

Also you can do: npm install npm run build (inside functions folder.)

Then firebase deploy.

Fixed it for me.

Answer 2

We were able to revert the dir-glob to 2.0.0 by adding:

"dir-glob": "2.0.0",
"globby": "8.0.0",

In the package.json dependencies.

You can do this with:

npm install [email protected] --save
npm install [email protected] --save

We then deleted the node_modules and run: npm install and deployed to Firebase
