Data Flow with Kafka data sets - Parse Error

I am trying to configure a data flow which can read data from Kafka topic. When I configure a long running thread to read from the topic, the below error is being thrown.

Note: Data posted to this topic is encrypted proto buff.

How does a data flow read data from topic? Does it try to parse it or will it place the payload on a temp page? Can we trace this read operation?
