Description

When trying to fetch a file from the device and turn it into a blob with default fetch shipped within RN 0.82.0, fetch issues a TypeError. Also other methods to fetch the file from the device fail.

The code used for this:

const response = await fetch(image.path)
const blob = await response.blob()

Response:

 Error: Uncaught (in promise, id: 1): "TypeError: Network request failed"

I used to used this throughout all RN versions I previously used and it doesnt work since upgrading from 0.73.6 to 0.82.0.
If I implement it with the formdata approach that I find on multiple sources, the upload succeeds but I get corrupted files.

      const formData = new FormData()

        formData.append('file', {
          type: mime.getType(image.path),
          uri: image.path,
          name: image.fileName,
        });

If I use the XMLHttpRequest approach I get errors as well.

To me it seems something changed regarding to accessing files/uri's on a device, yet I find 0 sources on it.
I changed all necessary permissions to match current latest approach.

I also added a reproducer with all 3 of the methods I described.
You will need an endpoint to upload a file for the reproducer.

Does anybody know what I am doing wrong?

Steps to reproduce
  1. install packages
  2. start app
  3. supply an api url to the fetch methods
  4. pick an image
  5. press upload image

Línea de trabajo

Comienza con el reproductor vinculado y ejecuta sus tres métodos de upload en Android con React Native 0.82.0, usando un endpoint de upload como se describe. Compara el mismo comportamiento de fetch con un archivo local y de blob con la versión reportada 0.73.6. La tarea está terminada cuando se haya identificado el comportamiento cambiado de las URI de archivo y se haya confirmado que el upload de archivos locales funciona, o se haya documentado la limitación admitida.
