How can i get the user data in Next JS Api Route Handler

"use server";
import { createClient } from "./server";

export async function getUser() {
  const supabase = await createClient();
  const {
    data: { user },
  } = await supabase.auth.getUser();
  if (!user) return null;

  const { data, error } = await supabase
    .from("users")
    .select("*")
    .eq("id", user.id)
    .single();

  if (error) {
    console.log("[GET LIB/GetUser.ts] ERROR", error);
    return null;
  }
  return data;
}

import { getUser } from "@/lib/supabase/getUser";
import { NextResponse } from "next/server";

export async function GET() {
  try {
    const user = await getUser()
    return NextResponse.json(user)
    
  } catch (error) {
    return NextResponse.json(error)
  }
}
