Sink connector with protobuf is not working!

[oviyan]

I have been trying to produce data using Javaclient and store data in postgres using sink-connector. i can post data into topic in protobuf format, but sink-connector seems not working. Just make sure that data being posted and available in topic, i built consumer in Java-client, and i can see data.

So data is there in topic, but something wrong with my sink-connector config. please find config details below, any help much appreciated!
