HMR does not work with React Native 0.49

[jurajkrivda]

I use React Native Navigation. When I do import 'haul/hot/patch'; in my index.js I am getting
undefined is not an object (evaluating slot[i].key) etc.

Have you seen the Manual Setup guide? Also, make sure you turn off Live Reload, when using HMR

[krizzu]

This is hopefuly fixed in #292

[jurajkrivda]

@krizzu still error with #master.
@thymikee yes of course I followed this tutorial https://github.com/callstack/haul/blob/master/docs/hmr/guides/react-native-navigation.md

[krizzu]

Hey @jurajkrivda
Could You please post full error (maybe a screenshot)? Thanks!

@krizzu
If the error is undefined is not an object (evaluating slot[i].key) and haul is from master/latest, it means that there's a module @jurajkrivda project that is breaking proxied components map. We can provide some guidance no how to find the breaking module, but it would be better if we had access to source.

@jurajkrivda
Can you post what dependencies are you using (from package.json)?

[krizzu]

@zamotany That's why I want to see a ss from red-box, so we can track it down. But yeah, source code would be better to debug, although I'm not convinced that @jurajkrivda's project is OS

@krizzu I use navigation from WIX. I started with this in my index.js:

import 'haul/hot/patch';
import './src';

[krizzu]

@jurajkrivda Thanks for your input!
I think we've localized the issue. We'll try to push fix today!

[zamotany]

@jurajkrivda Can you install Haul from this commit https://github.com/callstack/haul#f8d087e49401874ab8ceed2bf559b649f9fbc0ed? We cannot reproduce your error, so we need you to check if the fix is working fine.
