I'm trying to call a simple REST service with **fetch api** in **React Native**. I'm running the app on **Android**.

When I call `await response.json()` I get 

> 
> Unexpected token � in JSON at position 0
> 
> 
> 

, I tried also with `await response.text()`, and I get this text as result:

> 
> ��Mn�0��B�[C�bn�u��?@�+�bLR�ҌBR.�
>  �����H�ծ�͛�#?>�g���t�%{���Z��؄u�>fs0`]����H��'&��u�Z}��y�Z��2����i�d�G�>����R����6LL{j�j�7\���������d���L.���gٲXv�Lf��g�%T�~�\z�U8E܀���ڭ�c��@[G�;�T�������{�*�9�)��a½

This is the code I'm using:

```
export function fetchMenu() {
  return async(dispatch) => {
    try {
      dispatch(menuRequest(true));
      console.log(Institucion.aplent);
      var response = await fetch('http://<page_url>/api/moviles/personalizacion', {
        compress: true,
        headers: {
          'aplentId' : Institucion.aplent,
          'Accept-Encoding' : 'gzip,deflate'
        }
      });
      console.log(response);
      if(!response.ok) throw Error(response.statusText);
      var data = await response.json();
      console.log('Data:', data);
      dispatch(menuSuccess(data));
    }
    catch(ex) {
      console.log(ex);
      dispatch(menuFailure(ex));
    }
  };
}

```

Note: I've changed the url to for security reasons, but I have the correct url in code.

I've tried with and without the Accept-Encoding header, the same result.

**EDIT**

**If I disable deflate compression inside my REST API (on the server) it works ok, doesn't fetch support deflate compression?**
