I Have problem in react, I use fetch API from tutorial to get data from my API to show data on react, Here My JSON,

{
  "Konfigurasi": [
    {
      "id_konfigurasi": 1,
      "bahasa": "ID",
      "namaweb": "Universitas",
      "tagline": "home 2",
      "singkatan": "UBG",
      "id_user": 16,
      "periode_satu": "11 Desember 2023 s.d 30 April 2024 (Sudah Tutup)",
      "periode_dua": "1 Mei 2024 s.d 31 Juli 2024 (Sedang Dibuka)",
      "periode_tiga": "Belum Dibuka",
      "tanggal": "2023-05-10T02:44:44.000Z"
    }
  ]
}

And here my code.

const [configuration, setConfiguration] = useState([]);

async function getConfiguration(){  
const postData={
        method:"GET",
        headers:{"Content-Type":"application/json",}
    }

fetch(process.env.NEXT_PUBLIC_URL+'/api/Configuration',postData)
        .then(response => response.json())
        .then(data => setConfiguration(data))
        .catch(error => console.error(error));
}

useEffect(()=>{
    getConfiguration()
},[])

The Code was working, I try to console log the data it shows api array but when i try to send it to configuration, its show nothing, just empty array. It’s probably me missing something.

I try few tutorial and its not working, I want to put the JSON data into the Configuration variable, Is it from my code or i miss something ?
Thank You In Advance also I’am Sorry I’m not very good at English.
