Firebase Admin SDK with Netlify server side lambda

Hello

I have an SSR react app (Express) and my lambda functions work fine and all but connecting to the Firebase Real-Time database is a struggle. Google many answers which of none works.

I get several errors such as init standalone is not a function and “IDBIndex is not defined’,”

here is my code: (lamda fn)

import * as admin from 'firebase-admin'

const serviceAccount = require('../../my-saas-XXX.json')

admin.initializeApp({

  credential: admin.credential.cert(serviceAccount),

  databaseURL: 'https://my-saas.firebaseio.com',

})

export async function handler(event, context) {

  const body = JSON.parse(event.body)

  const {

    email,

    password,

    name,

    organisation,

    logo,

    phone,

    address,

    homepage,

    option,

  } = body

  console.log('body:::::::::::::::::::', body)

  const user = {

    email,

    name,

    organisation,

    logo,

    phone,

    address,

    homepage,

    option,

    admin: false,

    key_li: '',

    key_ga: '',

  }

  const db = admin.database()

  // console.log(db)

  console.log('user', user)

  return await admin

    .auth()

    .createUser({

      email: email,

      emailVerified: false,

      phoneNumber: phone,

      password: password,

      displayName: name,

      photoURL: 'http://www.example.com/12345678/photo.png',

      disabled: false,

    })

    .then((usr) => {

      db.ref('users/' + usr.uid)

        .set(user)

        .then(console.log('uid', usr.uid))

        .catch((error) => {

          console.log(error.message)

        })

      return {

        statusCode: 200,

        body: JSON.stringify({ data: usr.uid }),

      }

    })

    .catch((e) => {

      return {

        statusCode: 500,

        body: JSON.stringify({ data: e.message }),

      }

    })

}

I added a webpack.config.js which stance

module.exports = {
  resolve: {
    mainFields: ['main', 'module'],
  },
}
