Node SOAP, request gives empty soap body

I am using SOAP npm module to create a SOAP server. Then binding below module to /wsdl endpoint using soap module.

var dns = require('dns');

export default {
    MyService: {
        MyServicePortType: {
            MyFunction: function(args, callback) {
                console.log(args);
                if(!args.domain) {
                    return {
                        ip: 'Please pass a domain name like google.com'
                    }
                }else {
                    dns.lookup(args.domain, function (err, addresses, family) {
                        console.log(addresses, family);
                        callback({
                            ip: addresses
                        });
                    });
                }
            }
        }
    }
};

This is the WSDL I am using

<wsdl:definitions name="MyService" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:ns="http://localhost:3000/wsdl" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" targetNamespace="http://localhost:3000/wsdl">

   <wsdl:documentation>MyService</wsdl:documentation>

   <wsdl:types>
      <xs:schema attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="http://localhost:3000/wsdl">
         <xs:element name="IpRequest">
            <xs:complexType>
               <xs:sequence>
                  <xs:element minOccurs="0" name="domain" type="xs:string" />
               </xs:sequence>
            </xs:complexType>
         </xs:element>
         <xs:element name="IpResponse">
            <xs:complexType>
               <xs:sequence>
                  <xs:element minOccurs="0" name="ip" type="xs:string" />
               </xs:sequence>
            </xs:complexType>
         </xs:element>
      </xs:schema>
   </wsdl:types>

   <wsdl:message name="domainRequest">
      <wsdl:part name="parameters" element="ns:IpRequest" />
   </wsdl:message>
   <wsdl:message name="domainResponse">
      <wsdl:part name="parameters" element="ns:IpResponse" />
   </wsdl:message>

   <wsdl:portType name="MyServicePortType">
      <wsdl:operation name="MyFunction">
         <wsdl:input message="ns:domainRequest" />
         <wsdl:output message="ns:domainResponse" />
      </wsdl:operation>
   </wsdl:portType>

   <wsdl:binding name="MyServiceHttpBinding" type="ns:MyServicePortType">
      <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document" />
      <wsdl:operation name="MyFunction">
         <soap:operation soapAction="http://localhost:3000/wsdl/MyFunction" style="document" />
         <wsdl:input>
            <soap:body use="literal" />
         </wsdl:input>
         <wsdl:output>
            <soap:body use="literal" />
         </wsdl:output>
      </wsdl:operation>
   </wsdl:binding>

   <wsdl:service name="MyService">
      <wsdl:port name="MyServiceHttpsEndpoint" binding="ns:MyServiceHttpBinding">
         <soap:address location="http://localhost:3000/wsdl" />
      </wsdl:port>
   </wsdl:service>

</wsdl:definitions>

When I make a SOAP request from postman it is giving empty soap body in response,

Request

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://localhost:3000/wsdl">
  <soap:Body>
    <ns:IpRequest>
        <ns:domain>yahoo.com</ns:domain>
    </ns:IpRequest>
  </soap:Body>
</soap:Envelope>

Response

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"  xmlns:ns="http://localhost:3000/wsdl">
    <soap:Body/>
</soap:Envelope>

Console.log statement in MyFunction is also not executing. Is it because something is wrong in WSDL or soap request?

From soap client 0.34.0 bluebird promises are replaced by custom promisifying (see https://github.com/vpulim/node-soap/pulls/1125), where in the case of async service method with no parameter you should explicitly set the parameter to {} such that the soap body can be correctly written in the request. In my case this was client.GetProcessListAsync({}). I hope this helps anyone stumbling over the same issue ;)
