## Steps to reproduce the errors

### Clone the repo and install dependencies

git clone https://github.com/nextauthjs/next-auth-example.git
cd next-auth-example
npm i

Copy the .env.local.example file in this directory to .env.local (which will be ignored by Git):

cp .env.local.example .env.local

Add details for one or more providers (e.g. Google, Twitter, GitHub, Email, etc). When configuring your database you should also install an appropriate node_module.

We would be installing faunadb

npm uninstall sqlite3
npm i faunadb

#### FaunaDB

Add Ennironment variable **FAUNADB_SECRET_KEY** and assign your server key
Create the following Collections and Indexes in FaunaDB

**Collections:**
1. users
1. accounts
1. sessions
1. verificationRequests

**Indexes:**
1. index_users_id
1. index_users_email
1. index_accounts_providerId_providerAccountId
1. index_verificationRequests_token
1. index_sessions_id
1. index_sessions_sessionToken

### Install faunadb adapter and configure [..nextauth].js file as below

npm install --save-prod next-auth @next-auth/faunadb-adapter

**[...nextauth].js**

import NextAuth from "next-auth"
import Providers from "next-auth/providers"
import Adapter from "@next-auth/faunadb-adapter"
import faunadb from "faunadb"

const faunaClient = new faunadb.Client({
  secret: process.env.FAUNADB_SECRET_KEY,
});

// For more information on each option (and a full list of options) go to
// https://next-auth.js.org/configuration/options
export default NextAuth({
  // https://next-auth.js.org/configuration/providers
  providers: [
    Providers.Google({
      clientId: process.env.GOOGLE_ID,
      clientSecret: process.env.GOOGLE_SECRET,
    }),
  ],
  adapter: Adapter({faunaClient}),
  ...
})
