Unable to get response in JSON format after aggregation in WSO2 ESB

I have a proxy service to search a user in multiple systems and should return the combined responses in JSON format.I get the responses combined but instead of getting it in JSON format I get the responses in XML format. I can see JSON responses in WSO2 server logs as below:

However, I don't get response in JSON format after calling the proxy url. Below is my ESB configuration:

I get the response as below:

Please let me know how I can get the JSON response. Any help would be greatly appreciated.

You can set the messageType to application/json instead of application/xacml+json in outSequence and try.

<property name="messageType" value="application/json" scope="axis2" type="STRING" description="messageType"/>

Also there is no application/xacml+json message formatters and message builders shipped with WSO2 ESB by default. If you need to use these formats you have to write your own formatters and builders and configure them in axis2.xml file.
