at these 2 lines there is sample data hard coded into the message handlers:
https://github.com/Countly/countly-sdk-react-native/blob/master/Countly.js#L965
https://github.com/Countly/countly-sdk-react-native/blob/master/Countly.js#L722
The data should be passed through with exactly what was sent in from the sender, such as:
.setData(message.data);
