Unknown mediator referenced by configuration element: dataServiceCall

Hi I am trying to use Data Service Call. When I use it in any proxy service in wso2 I get an error Unknown mediator referenced by configuration element: dataServiceCall

https://apim.docs.wso2.com/en/latest/reference/mediators/dss-mediator/

I am following the link as mentioned above. Can someone guide me what am I doing wrong ?

Below is the code I have written

<?xml version="1.0" encoding="UTF-8"?>
<proxy name="TestData" startOnLoad="true" transports="http https local" xmlns="http://ws.apache.org/ns/synapse">
    <target>
        <inSequence>
            <dataServiceCall serviceName="Hello">
            </dataServiceCall>
            <respond/>
        </inSequence>
        <outSequence/>
        <faultSequence/>
    </target>
</proxy>

Solution

Probably this has to do with the version of the Integration Studio you are using. It seems the IDE is unable to find the DataServiceCall Mediator. First, try updating the Integration Studio referring this document. If that doesn't work, try using a newer version of the Integration Studio.

Once updated the Dataservicecall Mediator should be listed under the Mediators section.
