Hi Priya, It seems like you are getting a SOAP response with an empty body(<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";>< soapenv:Body/></soapenv:Envelope>) so that the JSON conversion fails. What is the requirement here to convert an empty SOAP message into a JSON? If you are getting an empty SOAP body for a delete operation, there's no point of converting it to a JSON, instead, you can return an HTTP status code(200).
