Insert Field Action
Provided by: "Apache Software Foundation"
Support Level for this Kamelet is: "Stable"
Adds a custom field with a simple language parsed value to the message in transit.
The extract field action expected an application/json content type.
If for example you have an array like '{ "foo":"John", "bar":30 }' and your action has been configured with field as 'element' and value as 'hello', you’ll get '{ "foo":"John", "bar":30, "element":"hello" }'
