Android crash tracking an object with an array.

When tracking an object that includes an array as property, on Android we are seeing a crash.

Error is:

Property objects must be flattened before being sent across the JS bridge.

Removing the array property fixes the problem.

Version is 0.10.0. React Native version is 0.59.10.

Thanks for the report! Heap doesn't support non-scalar property values at present, so the likely fix here is going to be to throw an exception on the JS side with a more meaningful error message. My suggestion is to flatten the array, eg via array.join(',').

Maybe mention it in the docs somewhere? Or is it already there and I missed it?

Could the Heap library fail gracefully instead of crashing the app when this happens?
