I have secret in my auth options but its says no secret. How can i fix that?

import NextAuth, { AuthOptions, SessionStrategy } from "next-auth";
import CredentialsProvider from "next-auth/providers/credentials";

const authOptions: AuthOptions = {
    secret: "i have secret in here",
    providers: [
        CredentialsProvider({
            name: "credentials",
            credentials: {},
            async authorize(credentials, req) {
                return null;
            }
        })
    ],
    session: {
        strategy: "jwt" as SessionStrategy
    },
    pages: {
        signIn: "/login"
    }
};

const handler = NextAuth(authOptions);

export { handler as GET, handler as POST }
