Cannot read property "find" of undefined react-native

Hello!

I am trying to set up subscriptions on a react-native app but i am receiving the following error:

This is the subscription handler which works perfectly on the web side:

const SubscriptionSocket = async (url, logger) => {
  const API_TOKEN = await AsyncStorage.getItem('API_TOKEN');

  return AbsintheSocket.create(
    new Socket(`${WS_URL}/socket`, {
      logger,
      params: { jwt: API_TOKEN }
    })
  );
}

function subscriptionHandler(subscriptionConfig, variables, cacheConfig, observer) {
  const socket = new SubscriptionSocket(WS_URL, (kind, msg, payload) => { 
    if (typeof payload !== 'undefined' && payload.subscriptionId) {
      observer.onNext({ data: payload.result.data });
    } else {
      if (process.env.NODE_ENV === 'development') {
        console.log(`${kind.toUpperCase()} ${msg}`, payload);
      }
    }
  });
  
  AbsintheSocket.send(socket, { operation: subscriptionConfig.text, variables });
  
  return { 
    dispose: () => socket.phoenixSocket.disconnect(() => {
      if (process.env.NODE_ENV === 'development') {
        console.log(`DISPOSE \n${subscriptionConfig.text}`);
      }
    })
  };
}

This is currently a blocker for us so any help would be appreciated.

I was returning a promise from the SubscriptionSocket constructor, sorry for posting the issue.
