If I use `org.apache.kafka.connect.storage.StringConverter` I get the
following for my topic data serialized with **JSON Schema**:
```
"\u0000\u0000\u0000\u0000\u0001{\"name\":\"temperatureCelsius\",\"value\":23.0,\"unit\":\"C\",\"utc\":1592805755142}"
```
The double quotes are escaped and I'm guessing the
`\u0000\u0000\u0000\u0000\u0001` at the beginning is the [Magic Byte/Schema
ID](https://docs.confluent.io/current/schema-registry/serdes-develop/index.html#wire-format)
thats encoded with the message.
I think what's happening when the value converter is set to
`JsonSchemaConverter` is that the message is serialized to a Java object (based
on the [JsonConverter
source](https://github.com/apache/kafka/blob/trunk/connect/json/src/main/java/org/apache/kafka/connect/json/JsonConverter.java)
I'm guessing Jackson JsonNode?) and that object gets passed directly to the
websocket output resulting in something like `Struct{key1=val1,key2=val2}`.
Whereas, with `StringConverter` the message (inlcuding the schema ID bytes) are
deserialized to a String object directly resulting in above ^^ funny looking
JSON.
I was poking around the camel connector codebase and saw transforms, would
it work to write a transform class to take the JsonNode object and format it to
a JSON string with the method `jsonNode.toPrettyString()` before sending it to
the websocket output? - or do I misunderstand what transforms are to camel 😅?
