   @obozhinov it looks to me that in the supervisor spec you are still referencing the schema registry but further up you wrote that you mounted the .desc as a file, could that be the reason why it fails?
   
   also note if you use a file type protobuf decoder, the message payload is expected to be the plain protobuf data; but if you use schema registry, there should be a 5 byte preamble [from the schema registry wire format](https://docs.confluent.io/platform/current/schema-registry/fundamentals/serdes-develop/index.html#wire-format)
