TypeError: Cannot read property 'undefined' of undefined

@philglazer I have a similar error, I was curious how it happens so I opened up react-native-web-player, from where I saw error message in my console.log

It turns out that GET /fav.ico 404 is the error.

Thus I go ahead and check on google, it seems to be a well-acknowledged problem. It seems during next Chrome update, Chrome will support "disabling fetching fav.ico".

With that, I guess we could just shift to another browser for the moment. I'm using Firefox, and all react-native player goes perfectly well.

=======================================

Now, there's another possibility for this error: you enabled some extensions that injects react code. Disable them and you are good to go. (in my case, I have a Metamask extension, Ethereum wallet running on react, once I disable it. things are fine)

Hope it helps
Cheer.

The screenshot you posted is from https://facebook.github.io/react-native/docs/flexbox.html. I have not seen this error yet, on Chrome or Firefox. Can you share a bit more information about your browser and OS? Does this repro for anyone else?
