javascript - React Native: No propType for native prop RCTView.maxHeight

Question

After upgrading to RN 0.30 I started seeing the error shown below even when building the simplest possible app:

react-native init AwesomeProject
react-native run-ios

• The strangest is that components BlurView, VibrancyView and RNSearchBar are included in the warning messages despite the project not using them.
• Recompiling/cleaning the project doesn't fix the problem.

Console & error:

If you haven't changed this prop yourself, this usually means that your versions of the native code and JavaScript code are out of sync. Updating both should make this error go away.

Answer 1

The reason for this error was that another instance of React packager (still on 0.28) was running in the background at the time after I updated to 0.30.

Restarting React packager solved the problem.
