Deserialize JSON with Camel Routes

Question

I'm trying to unmarshal json data generated by debezium inside a kafka topic.

My approach is simple, use POJOs and Jackson Library, however, since this json has a root object (initialized inside "{}") it throws an error.

This is the json received, I'm just interested on the payload:

{
    "schema": {
        "type": "struct",
        "fields": [{
            "type": "double",
            "optional": false,
            "field": "codid"
        }, {
            "type": "string",
            "optional": true,
            "field": "__op"
        }, {
            "type": "string",
            "optional": true,
            "field": "__deleted"
        }],
        "optional": false,
        "name": "demo.RESCUE.Value"
    },
    "payload": {
        "codid": 0.0,
        "__op": "r",
        "__deleted": "false"
    }
}

And this is my Route:

public class Routes extends RouteBuilder{

    public static class MySplitter {
        public List<Payload> splitBody(Rescue data) {
            return data.getPayload().stream().collect(toList());
        }
    }

    @Override
    public void configure() throws Exception {

        from("kafka:{{kafka.source.topic.name}}?brokers={{kafka.bootstrap.address}}&autoOffsetReset=earliest")
        .log("Received body: ${body}")
            .unmarshal().json(JsonLibrary.Jackson, Rescue.class)
            .split().method(MySplitter.class, "splitBody")
            .marshal().json(JsonLibrary.Jackson)
            .convertBodyTo(String.class)
            .log("Output: ${body}");
    }
    
}

And the error received:

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize value of type `java.util.ArrayList<org.demo.pojos.rescue.Payload>` from Object value (token `JsonToken.START_OBJECT`)
