With the image: confluentinc/cp-enterprise-control-center:6.1.0
when I click on the download button ( to download a message inside a topic )
the json file is correct except that the key ( a primitive avro key ) is not deser
[{"topic":"aaaa","partition":2,"offset":0,"timestamp":1621091829948,"timestampType":"CREATE_TIME","headers":[],"key":"\u0000\u0000\u0000\u0000\u0002\u000ede3a3f5","value":{"event_timestamp":123442,"event_datetime":"18","event_id":"aaaaaaaaaa","product_id":356}}]
in the UI of control-center the message key is well show ( deser )
Key : de3a3f5
So all avro primitives are not deser , if you open with google chrome , you will see that even in the UI the string is prefixed of unknow bytes.
control-center have exactly the same problem that AKHQ
bug still present in release 7.0.0 !!
seriously you do not use AVRO ???

AKHQ →
