I have a springboot application with apache camel. In it I have a camel-context.
I am trying to send json through curl with a key pair value and processing it through a route.

Sending the data:

```
curl --header "Content-Type: application/json" -X POST -d '{"msgId=EB2C7265-EF68-4F8F-A709-BEE2C52E842B", "ticket":"ERR001"}' http://lcalhost:8888/api/erroradmin

```

Camel-context.xml:

```

            <dataFormats>
                <!-- here we define a Json data format with the id jack and that it should use the TestPojo as the class type when
                     doing unmarshal. The unmarshalTypeName is optional, if not provided Camel will use a Map as the type -->
                <json id="jack" library="Jackson" unmarshalTypeName="java.util.HashMap"/>
            </dataFormats>

            </restConfiguration>

            <rest path="/api/erroradmin">
                <get uri="{id}">
                    <to uri="direct:processErrorAdminGet"/>
                </get>
                <post>
                    <to uri="direct:processErrorAdminPost"/>
                </post>
            </rest>

            <route id="processErrorAdminPost">
                <from uri="direct:processErrorAdminPost"/>
                <log message="Route(processErrorAdminPost): ${body}"/>
                <unmarshal>
                    <custom ref="jack"/>
                </unmarshal>
                <log message="Route(processErrorAdminPost): ${body}"/>

            </route>
        </camelContext>
    </beans>

```

I am getting the following Stacktrace:
