Need help integrating auth0 with authjs

[subhajit-aec]

I am using auth0 as the provider.
This my auth0 flow 👇. So for the first time user I want to validate the email

exports.onExecutePostLogin = async (event, api) => {
    if (!event.user.email_verified) {
        api.access.deny('Please verify your email before logging in.');
    }
};

This is my auth.ts file

import NextAuth from "next-auth";
import Auth0 from "next-auth/providers/auth0";

export const { handlers, signIn, signOut, auth } = NextAuth({
  providers: [
    Auth0({
      clientId: process.env.AUTH_AUTH0_ID,
      clientSecret: process.env.AUTH_AUTH0_SECRET,
      issuer: `https://${process.env.AUTH_AUTH0_ISSUER}`,
      authorization: {
        params: {
          prompt: "login",
        },
      },
    }),
  ],
  secret: process.env.AUTH_SECRET,
  pages: {
    error: '/error',
  },
  
});

So I am expecting to redirect the error to the error page.
But it's throwing this error 👇
[auth][error] OAuthCallbackError: OAuth Provider returned an error. Read more at https://errors.authjs.dev#oauthcallbackerror

GET /api/auth/callback/auth0?error=access_denied&error_description=Please%20verify%20your%20email%20before%20logging%20in. 302 in 626ms
GET /api/auth/signin?error=OAuthCallbackError 200 in 31ms

It's redirecting to the signin page given by authjs

How to fix this and handle this kind of scenario?
