Same code works fine in "react native".

But it doesn't work on the web;

Code:

const target = event.target as HTMLInputElement;

const file: File = (target.files as FileList)[0];

const response = await fetch(file);

  const body = await response.blob();

  await fetch(signedUrl, { method: 'PUT', body, })
    .then(() => {

      console.log('aws succes');

    })
    .catch((err) => {

      console.log('aws', err);

    });

Console:

 TypeError: Failed to Fetch
