Issues After Upgrading to SDK 42

Expo SDK
1

Please provide the following:

  1. SDK Version: 42.0
  2. Android/iOS

In order to be able to test an app on an iPhone 12 in Expo Go I needed to update my Expo SDK version. We were at 38 (which was no longer supported).

So today I updated the expo-cli and then updated to SDK 42. Eventually I was able to get the app to compile, and I can login successfully and navigate back and forth between various screens.

However, when I load one particular screen I end up with this error:

TypeError: undefined is not a function (near '..._reactNativeReanimated.default.interpolate...')
    
This error is located at:
    in NavigationContainer (at App.js:42)
    in RCTView (at View.js:34)
    in View (at App.js:40)
    in Provider (at App.js:39)
    in App (created by ExpoRoot)
    in ExpoRoot (at renderApplication.js:45)
    in RCTView (at View.js:34)
    in View (at AppContainer.js:106)
    in DevAppContainer (at AppContainer.js:121)
    in RCTView (at View.js:34)
    in View (at AppContainer.js:132)
    in AppContainer (at renderApplication.js:39)

After doing some additional testing, it seems the issue is in the TabView block of this one component. When I comment this section out, the component will load without any errors.

This is the relevant TabView code:

  <TabView
    swipeEnabled={false}
    navigationState={this.state}
    renderScene={SceneMap(this.state.tabSceneMap)}
    onIndexChange={index => this.setState({ index })}
    renderTabBar={this._renderTabBar}
    tabBarPosition='bottom'
    initialLayout={{ flex: 1 }}
  />

Is some of the syntax outdated here? Something else? Any insight would be appreciated.

Hey @darrenbrettking, I would recommend taking a look into the changes that occurred regarding react-navigation, react-native-screens and react-native-reanimated between SDK38 and 42. Most of the big changes are detailed in the SDK41 blog post.

Cheers,
Adam
