drop field action Drop Field Action

Provided by: "Apache Software Foundation"

Support Level for this Kamelet is: "Stable"

Removes a custom field by given name from the message in transit.

The drop field action expects an application/json content type.

If for example you have an object like '{ "foo":"John", "bar":30, "element":"hello" }' and your action has been configured with field as 'element', you’ll get '{ "foo":"John", "bar":30 }' as a result because the field 'element' has been removed.
