Error: This action with HTTP GET is not supported by NextAuth.js

I've configured everything on the WordPress side and seems everything is working perfect, I'm trying to connect using the next auth client and I get this error. When I click the sign in button I get redirected to the url https://mydomain.local/api/auth/callback?code=182cdfefe65de7bc15acb4619e44b6e0ac1a98aa&state=AUDGKCrDKzaNyTLeMf_6J8-3b6jWHd4d24-WTYSsNcE

so the WordPress oauth server is generating the code and while redirecting back to this page it says "Error: This action with HTTP GET is not supported by NextAuth.js"

Below is my next auth route file inside mydomain/app/api/auth/[...nextauth]/route.ts

i'm using

```
"next": "13.4.12",
"next-auth": "^4.22.3",
```

I'm unsure if this is a next-auth thing or i'm not sending something useful to the WordPress OAuth server

```
import NextAuth, { NextAuthOptions } from 'next-auth';

const authOptions: NextAuthOptions = {
providers: [
{
id: 'mydomain',
issuer: 'https://myoauthdomain.com/',
wellKnown: "https://myoauthdomain.com/.well-known/openid-configuration",
clientId: "XktKsfkYP2zq6cgaLZbH",
clientSecret: 'C4EQe4ptNuyR+NsK3vEOhW2dKDEVRpRODXEuZv07bXk=',
idToken: true,
name: 'myauthdomain',
type: 'oauth',
authorization: {
url: 'https://myoauthdomain.com/wp-json/openid-connect/authorize',
params: {
scope: "openid profile",
redirect_uri: 'https://mydomain.local/api/auth/callback'
}
},
token: {
url: 'https://myoauthdomain.com/wp-json/openid-connect/token',
params: {
grant_type: 'authorization_code',
redirect_uri: 'https://mydomain.local/api/auth/callback'
},
},
profile(profile) {
return { ...profile }
},
},
],
debug: true,
callbacks: {
async jwt({ token, account }) {
return token
},
async session({ session, token, user }) {
return session
},
},
}

const handler = NextAuth(authOptions);

export { handler as GET, handler as POST };
```
am i missing something to pass to the server or is it something related to next-auth thing? please help

Start with the reported mydomain/app/api/auth/[...nextauth]/route.ts configuration and trace the callback request returned by the WordPress OpenID Connect authorize endpoint. Compare the callback, authorization, and token URLs with the server's documented flow and NextAuth.js 4.22.3 behavior. Done means the sign-in callback completes without the HTTP GET error, with the relevant request and response details documented.
