を独立した関数として切り出しただけ

に移行したことで、cookieを使ったuploadができなくなった？

export async function uploadToGyazoEasyAuth({dataURI, clientId, title}) {
  const formData = new FormData();
  //console.log({dataURI, clientId, title});
  formData.append('image_url', dataURI);
  formData.append('client_id', clientId);
  formData.append('referer_url', location.href);
  formData.append('title', title);
  
  const easyAuth = await fetch(
    'https://upload.gyazo.com/api/upload/easy_auth',
    {
      method: 'POST',
      mode: 'cors',
      credentials: 'include',
      body: formData,
    },
  );
  const {get_image_url} = await easyAuth.json();
  return (await fetch(get_image_url, {
    mode: 'cors',
    credentials: 'include',
  })).url;
}
