I am using Next.js v14 and next-auth v5 beta.
I have this in my route.tsx placed in app/api/auth/[...nextauth]/ directory:

import NextAuth from "next-auth";
import AzureADProvider from "next-auth/providers/azure-ad";

export const {
    handlers: { GET, POST },
    auth,
    signIn,
    signOut,
} = NextAuth({
  providers: [
    AzureADProvider({
      clientId: process.env.AZURE_AD_CLIENT_ID,
      clientSecret: process.env.AZURE_AD_CLIENT_SECRET,
      tenantId: process.env.AZURE_AD_TENANT_ID,
    })
  ]
})

When deploying to azure webapp, I get this error in the build process which is next build:

app/api/auth/[...nextauth]/route.tsx
Type error: Route "app/api/auth/[...nextauth]/route.tsx" does not match the required types of a Next.js Route.
  "auth" is not a valid Route export field.
