React Native SocketProtocol Error and TimeoutError

Question

I can't seem to figure this out at all. When ever I open my React Native application I get these errors. The best I have found is that it's something to do with how the applications is being bundled. Any help would be much appreciated and upvoted! Thanks!

Errors from xCode

Answer 1

After a long time, I realized it was actually my React Dev Tools and HMR. I had to update my Store Configure to the following:

OLD ----- (BELOW)

    import Immutable from 'immutable';
    import { Platform } from 'react-native';
    import { createStore, applyMiddleware, compose } from 'redux';
    import thunk from 'redux-thunk';
    import reducer from '../reducers';

    const middlewares = [thunk]; 

let enhancer;
if (__DEV__) {
  const installDevTools = require('immutable-devtools');
  installDevTools(Immutable);

  const devTools = require('remote-redux-devtools');
  enhancer = compose(
    applyMiddleware(...middlewares),
    devTools({
      name: Platform.OS,
      hostname: 'localhost',
      port: 5678
    })
  );
} else {
  enhancer = applyMiddleware(...middlewares);
}

NEW----- (BELOW)

import Immutable from 'immutable';
import { Platform } from 'react-native';
import { createStore, applyMiddleware, compose } from 'redux';
import thunk from 'redux-thunk';
import reducer from '../reducers';

const middlewares = [thunk];

let enhancer = applyMiddleware(...middlewares);

export default function configureStore(initialState) {
  const store = createStore(reducer, initialState, enhancer);
  if (module.hot) {
    module.hot.accept(() => {
      store.replaceReducer(require('../reducers').default);
    });
  }
  return store;
}
