Why is this build error occuring when running npm-run-build?
In src/app/api/auth/[...nextauth]/route.ts

export const authOptions: NextAuthOptions = {
  providers: [
    CredentialsProvider({
      name: "Credentials",
      credentials: {},
      async authorize(credentials, _req) {
        const URL = String(env.NEXT_PUBLIC_API_URL) + "/account/login/";
        const { email, password } = credentials as { email: string, password: string };

        const res = await loginUser(URL, { email, password });
        if (res.ok) return await res.json().data;        
        return null;
      }
    })
  ],
  callbacks: {
    async session({ session, token }: any) {
      session.access = token.access
      session.refresh = token.refresh

      if (session?.access ?? false) {
        const URL = String(env.NEXT_PUBLIC_API_URL) + "/account/me/"

        const res = await getUserDetail(URL, token.access);

        if (res.ok) {
           // logic
        }
      }

      return session
    },
    async jwt({ token, user }: any) {
      if (user) {
        // logic
      }

      if (!user) return refreshAccessToken(token)
      return token
    }
  },
  pages: { signIn: '/login' }
}

const handler = NextAuth(authOptions);
export { handler as GET, handler as POST }

The error I got during build is attached as an image.
Can anyone help me solve this issue? Thanks for reading.
