React-native-navigation: [V2] Cannot read property 'topTabs' of undefined

[Burnsy]

Issue Description

I have updated my RN project from V2.0.2242 to V2.0.2349, and on iOS it is failing to load the application, when checking debug it shows a warning of "Cannot read property 'topTabs' of undefined"

Checking though my application, I have not got topTabs defined anywhere. If i need to define it where would I define it? Thank you.

I had a similar issue. Have you added root at the top level when invoking setRoot.

Navigation.setRoot({
  root: {
    // whatever you had before
  },
})

After changing this, the issue you mentioned went away but then I got a new issue, see below...

Exception '-[__NSCFBoolean countByEnumeratingWithState:objects:count:]: unrecognized selector sent to instance 0x10ef946b0' was thrown while invoking setRoot on target RNNBridgeModule with params (...

Update

I was able to resolve the next issue by adding root to the top level object for setDefaultOptions

Navigation.setDefaultOptions({
  root: {
    // whatever you had before
  },
})

_BTW It looks like your RN & RNN versions ar flipped_

The main problem was two changes that happened:

{ statusBarStyle: 'light', largeTitle: true }

Ara now invalid options. You should use:

{ statusBar: { visible: true }, largeTitle: { visible: true }, }

After fixing it you can use setRoot.

@gabrielvcbessa ya I just noticed that myself. Thanks for the update! 👍
