Android: Cannot invoke method get() on null object

[brianephraim]

"react-native": "0.60.5",
"@brandingbrand/react-native-leanplum": "^4.0.0",

Android build fails with:

Could not determine the dependencies of task ':@brandingbrand_react-native-leanplum:mergeReleaseResources'.
> Failed to notify dependency resolution listener.
   > Cannot invoke method get() on null object
   > Cannot invoke method get() on null object

I can get it to build by commenting out the lines shown below.

/node_modules/@brandingbrand/react-native-leanplum/android/build.gradle

dependencies {
    compile "com.facebook.react:react-native:+"
    compile 'com.leanplum:leanplum-fcm:5.2.3'
    // compile 'com.google.firebase:firebase-messaging:17.5.0'
    
    compile 'com.leanplum:leanplum-location:5.2.3'
    // compile "com.google.android.gms:play-services-location:17.0.0"
}

This problem does not exist in version 3.0.1
