Camel - Poll rest endpoint and split JSON list - apache-camel

Question

So I have a rest API that lives at https://foo.bar/api which returns either an empty json list [] or a list that contains 1 or more items:
[
{
"#class": "foo.bar.java.MyObject",
"name": "Joe Bloggs"
},
{
"#class": "foo.bar.java.MyObject",
"name": "Fred Flinstone"
}
]
Now I am trying to have camel take in this data from my endpoint and hand each object within the list to a processor. I've tried the following:
fromF("timer://foo-poll?fixedRate=true&delay=5s&period=%d&bridgeErrorHandler=true", pollRate)
.toF("https4://%s/%s", host, requestPath)
.log("Received: ${body}")
.split()
.jsonpath("$")
.log("Split: ${body}")
.process(barProccessor);
As well as various attempts to unmarshal the data using .unmarshal(new ListJacksonDataFormat(MyObject.class)) or .unmarshal().json(JsonLibrary.Jackson, List.class)
where nothing has worked.
Using the larger code block above, there are no errors nor is the "Split: ${body}" log message printers out.
Unmarshalling using either methods described above throws this regardless of how many items are returned from the API:
com.fasterxml.jackson.databind.exc.MismatchedInputException: No
content to map due to end-of-input
When there

Answer 1

Okay, managed to figure this out if anyone else is facing a similar issue. The working route builder:
fromF("timer://foo-poll?fixedRate=true&delay=5s&period=%d&bridgeErrorHandler=true", pollRate)
.toF("https4://%s/%s", host, requestPath)
.log("Received: ${body}")
.streamCaching("true")
.unmarshal(new ListJacksonDataFormat(MyObject.class))
.split()
.jsonpath("$")
.log("Split: ${body}")
.process(barProccessor);
I have enabled stream caching and unmarshalled the list using Jackson.
