For who want the answer, you only have to change the output tag from <wps:RawDataOutput> to <wps:Output> like this:
<wps:ResponseDocument storeExecuteResponse="true" status="true"> <wps:Output mimeType="application/json"> <ows:Identifier>result</ows:Identifier> </wps:RawDataOutput>Output> </wps:ResponseDocument>
