Attempt to invoke interface method 'boolean com.google.common.util.concurrent.ListenableFuture.cancel(boolean)' on a null object reference

I am trying to figure out how to get sensors data from Health Services on Wear OS.

I'm trying to run samples (Passive Data Sample) from the official guide on Emulator for Wear OS API 30 (He is available in Beta Android Studio Arctic Fox), but I get this error:

Has anyone faced a similar problem?

You just need to update this package

react-native-reanimated

npm i [email protected]

after installing this version of the package, just restart your simulator.

change enableHermes from false to true in your android/app/build.gradle file

project.ext.react = [
    enableHermes: true
]

add these line in android/app/src/main/java/com/yourProjectName/MainApplication.java

import com.facebook.react.bridge.JSIModulePackage;
import com.swmansion.reanimated.ReanimatedJSIModulePackage;

@Override
protected JSIModulePackage getJSIModulePackage() {
    return new ReanimatedJSIModulePackage();
}
//if this is not exist then also add this
@Override
protected String getJSMainModuleName() {
    return "index";
}

and rebuild the project
