TypeError: null is not an object (evaluating 'ReactNativeFlurry.initBuilder')

[sansavision]

Describe the bug In index.js where we init the builder results in a crash. Error message: TypeError: null is not an object (evaluating 'ReactNativeFlurry.initBuilder') which then crashes the app with When we uncomment the flurry builder, it works. We have used flurry for a long time with no issues.

Environment Please tell us the versions of SDKs you are using. If you are not sure about React Native version, you can run react-native --version under your project.

• React Native version: "0.69.5",
• react-native-flurry-sdk version: "7.3.0",

To Reproduce Steps to reproduce the behavior:

1. create react native project
2. in the index js, init the builder new Flurry.Builder() .withCrashReporting(true) .withLogEnabled(true) .withLogLevel(Flurry.LogLevel.DEBUG) .build(FLURRY_ANDROID_API_KEY, FLURRY_IOS_API_KEY);

Error message: TypeError: null is not an object (evaluating 'ReactNativeFlurry.initBuilder') app crashes with invariant view error. """ Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication). A frequent cause of the error is that the application entry file path is incorrect. This can also happen when the JS bundle is corrupt or there is an early initialization error when loading React Native. """

When we uncomment the flurry builder, everything works well.

@sansavision Are you using Expo? Please refer to https://github.com/flurry/react-native-flurry-sdk/issues/31

Expo does NOT support or manage custom native libraries except their own build-in.

[sansavision]

Hi

No we are not using expo.

@sansavision Do you have the same issue for Android?

We have used flurry for a long time with no issues.

Issue did not happen for the previous react-native-flurry-sdk versions?

[sansavision]

I remember it working on older versions. No problem with the android version.

@sansavision Thanks for the info! There is a known issue in the iOS native version 12.0.0. While we are working on the solution, could you please go back to use react-native-flurry-sdk versions 7.1.1? And please let us know whether it resolves your issue or not. Thanks!

[sansavision]

@poting-oath ok, i will try it and let you know. Thanks.

Figured out what the problem was. For some reason the sdk was not automatically installed with pod install, I had to manually add it: pod 'react-native-flurry-sdk', :path => '../node_modules/react-native-flurry-sdk/ios' in the pod file. But now the latest version works. I suggest you check if this is a common issue or maybe it was a limited issue with my specific build. Cheers

Looks like newer React Native's Autolinking is no longer working here! It only looks up the .podspec file at the project root folder (ignores the ios subfolder).

@sansavision Fix is released in version 8.0.0. Thanks for your help!
