try {
const response = await fetch(url, {
      method: 'GET',
      headers: {
        'Content-Type': "application/json",
        'Accept': 'application/json'
      }
    });
} catch (err) {
  console.log(err)
}

you need to modify like below

fetch(url)
  .then((resp) => resp.json()) // Transform the data into json
  .then(function(data) {
    // your code logic with the response
    })
  })
