This is working fine for me
// app/src/app/api/auth/[auth0]/route.ts
import { handleAuth, handleLogout } from '@auth0/nextjs-auth0'
export const GET = handleAuth({
logout: handleLogout({ returnTo: 'http://localhost:3000/api/auth/login' }),
})
You need to define logout url which you pass in returnTo in Auth0 dashboard like http://localhost:3000/api/auth/login
