   Hi @dhanendras, and thanks for sharing you experience with camel-quarkus. I 
agree with Luca's view on this ticket.
   I played a bit with a route like:
   ```
   
rest().post("/submitodc").consumes(MediaType.MULTIPART_FORM_DATA).to("direct:uploadReportProcessor");
   from("direct:uploadReportProcessor").process(e -> 
e.getMessage().setBody(Map.of("name", "e")));
   ```
   And indeed, we hit an issue as there are no pre-registered 
[converters](https://camel.apache.org/manual/latest/type-converter.html) to 
translate a `Map` to a `ByteBuffer`.
   
   In such situation, one may end up using 
[camel-quarkus-gson](https://camel.apache.org/camel-quarkus/latest/extensions/gson.html)
 as below:
   ```
   process(...).marshal().json(JsonLibrary.Gson);
   ```
   
   Or maybe a [custom 
converter](https://camel.apache.org/manual/latest/type-converter.html#TypeConverter-Addtypeconverterclassesatruntime)
 similar to this:
   ```
   public void configure() {
     getContext().getTypeConverterRegistry().addTypeConverters(new 
MyCustomConverters());
     ...
   }
   
   @Converter
   public static class MyCustomConverters implements TypeConverters {
     @Converter
     public ByteBuffer toByteBuffer(HashMap<?, ?> map) {
       return ByteBuffer.wrap(...);
     }
   }
   ```
   Does it make sense for you ?
