react native fetch returns Blob instead of JSON after upgrading to 0.24.1

I probably should have read over https://github.com/github/fetch before posting this question...

Need to use .json() on the response.

return fetch(`${auth0_api}/userinfo`, {
  method: 'GET',
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/json',
    'Authorization': `Bearer ${access_token}`
  }
})
.then((response) => {
  return response.json();
});

Fetch library has been updated, now is:

fetch('/users')
.then(function(res){
    res.json().then(function(data) {
       console.log('request succeeded with JSON response', data)
    }).catch(function(error) {
       console.log('Data failed', error)
    });
}).catch(function(error){
     console.log('request failed', error)
})
