Need a solution to decompress the data object on payload.
JField(
// "data",
// JString(Base64.getEncoder.encodeToString(compressString(data)))
// )

we need a scala function to decode the zip compressed Data part. Can you have a util class/method to do that?

{"counters":{"messageCounter":31,"payloadCounter":2},"data":"H4sIAAAAAAAA=="}
