Hi Kanishka,

It would be helpful if you can share the payload factory configuration. The
scenario works fine according to the below configuration.

<api xmlns="http://ws.apache.org/ns/synapse" name="arrayCheck"
context="/check1">
   <resource methods="POST">
      <inSequence>
         <payloadFactory media-type="json">
            <format>               {"outerbody" : $1}            </format>
            <args>
               <arg evaluator="json" expression="$"/>
            </args>
         </payloadFactory>
         <respond/>
      </inSequence>
   </resource>
</api>

Regards,
Arunan
