How to do Json to Json transformation in apache camel karavan?
I want to generate a new message with an existing message and some extra fields. Like wso2 payload factory mediator. How we achieve it in our apache camel karavan ?

I use this one:

1. Use Unmarshall to convert JSON to Object
2. Create output Object using setBody and Groovy Expression
3. User Marshall to convert Object to JSON

Another option: https://github.com/apache/camel-kamelets-examples/tree/main/jbang/json-transform

I tried out the GitHub example you suggested, and it's working fine! Thanks a bunch for sharing.
