I'm struggling with a REST DSL. It handles a POST request for a file
upload, so the request body is binary type, and the response is JSON
describing the result. The container is Jetty.
My DSL looks like this:
rest("/rest/v1/datasets")
.post().description("Upload file to create new dataset")
.bindingMode(RestBindingMode.off)
.produces("application/json")
.route()
.to("direct:process_the_body") // this processed the body and
returns a result object
.marshal().json(JsonLibrary.Jackson) // which here is converted to JSON
.log("marshal complete. JSON is ${body}")
.endRest()
Its all working fine, and the JSON gets marshalled correctly (the log()
statement
By the request fails with this error:
[qtp562561015-19] INFO route2 - marshal complete. JSON is
{"id":13,"name":"big_bad","size":null,"metadata":{"type":"ITEM","className":"java.util.stream.ReferencePipeline$Head","size":1},"created":1434992702164,"updated":1434992702164,"loid":333226}

Any ideas what's wrong?
