firebase createUserWithEmailAndPassword wrong error on ios

[atlanteh]

We have firebase up and running in our app. We tried adding fetch-blob to add files to firebase storage.
However suddenly firebase started producing us wrong message on createUserWithEmailAndPassword.

Normally when we create a user with createUserWithEmailAndPassword, the Promise should reject with error.code "auth/email-already-in-use" when the email is already in use.
However when adding fetch-blob, firebase suddenly takes quite a few seconds to return and has error.code "auth/network-request-failed" .
This happens only if the polyfill is added and only in ios.

Running the following code twice fails for us:

import firebase from '../Services/firebase'; // firebase with auth..
import RNFetchBlob from 'react-native-fetch-blob';

const polyfill = RNFetchBlob.polyfill;

window.XMLHttpRequest = polyfill.XMLHttpRequest;
window.Blob = polyfill.Blob;

const email = 'test@gmail.com';
const password = '123456';
const firebaseAuth = firebase.auth();
firebaseAuth.createUserWithEmailAndPassword(email, password)
.catch(err => {
    alert(error.code); // Should be "auth/email-already-in-use". Instead we get "auth/network-request-failed"
});

Versions
react-native-fetch-blob: 0.9.4
react-native: 0.32.0

Thanks for your reporting, I will look into this issue and update the status in this thread.

@atlanteh , I've confirmed that t reason why the error message inconsistency between Android and IOS is because IOS throws error when status code is not 2xx but Android does not, I've changed IOS implementation and published a new release 0.9.5-beta.3, please try install the version and see if the problem got fixed 😄

$ npm install --save react-native-fetch-blob@0.9.5-beta.3
$ react-native link

Yes. It solves the problem :)
