KSQL interpreter

Hi guys,
I'm building a KQL interpreter. KSQL is the streaming SQL engine that
enables real-time data processing against Apache Kafka topics.
I created an interpreter that leverages the InterpreterOutputStream class
in order to stream the result from the backend to the frontend, but I get
the following representation in the frontend:

What am I doing wrong?

Following the Interpreter implementation:

Thanks a lot

Andrea
