opts is not defined

Hi is this correct? where does opts come from?

const photos = [photo1, photo2, ...]
photos.forEach((photo) => {
    data.append('photo', {
    uri: photo.uri,
    type: 'image/jpeg', // or photo.type
    name: photos.name
  });  
});
fetch(url, opts);

should it be data? thanks
