Hi, trying to add NextAuth support to a dynamic subdomain website. Currently I'm trying to get it to work so

http://851129766299041802.localhost:3020/api/auth/signin works but it redirects back to http://localhost:3020/api/auth/signin?error=MissingCSRF

I'm using NextAuth "next-auth": "^5.0.0-beta.25"

Route.ts

// src\app\api\auth\[...nextauth]\route.ts
import { handlers } from "@/auth";
export const { GET, POST } = handlers;
import { handlers } from "@/auth";
export const { GET, POST } = handlers;

// src\auth.config.ts
// auth.config.ts
import { NextAuthConfig } from "next-auth";
import Discord from "next-auth/providers/discord";

export const authConfig: NextAuthConfig = {
  callbacks: {
    async authorized({
      auth,
      request: { nextUrl },
    }: {
      auth: any;
      request: { nextUrl: URL };
    }) {
      const isLoggedIn = !!auth?.user;
      const isOnProtected =
        !nextUrl.pathname.startsWith("/login") &&
        !nextUrl.pathname.startsWith("/api/auth");
      if (isOnProtected) {
        if (isLoggedIn) return true;
        return false;
      } else if (isLoggedIn) {
        return true;
      }
      return true;
    },
  },
  providers: [
    Discord({
      clientId: process.env.DISCORD_CLIENT_ID,
      clientSecret: process.env.DISCORD_CLIENT_SECRET,
    }),
  ],
};

export default authConfig;

// src\auth.ts
import { AuthConfig, NextAuth, Lib } from "@/.";
import { headers } from "next/headers";
export const { auth, handlers, signIn, signOut } = NextAuth(async () => {
  const reqHeaders = headers();
  const settings = await Lib.settings.getSettingsByDomain(
    reqHeaders.get("host") as string
  );
  if (AuthConfig?.providers[0]?.options) {
    AuthConfig.providers[0].options.clientId = settings?.["auth-client-id"];
  }
  if (AuthConfig?.providers[0]?.options) {
    AuthConfig.providers[0].options.clientSecret =
      settings?.["auth-client-secret"];
  }
  return AuthConfig;
});

// src\middleware.ts
import NextAuth from "next-auth";
import { authConfig } from "./auth.config";

export default NextAuth(authConfig).auth;

export const config = {
  matcher: ["/servers(.*)", "/dashboard(.*)"],
};
