npm soap with auth header - node.js

Question

I am attempting to us the npm soap package to create a series of endpoints to a remote server that I can interface with through angular 4. I have read the documentation, but I am still unclear with regards to its usage. Below is the WSDL. How do I create a client that I can use to interface with the endpoint below? Here is the WSDL.
http://208.180.122.191:8081/niku/wsdl/Query/ts_pending_approvals?tenantId=clarity
My expectation is that I should get a response with the following:
var soap = require('soap');
var url = 'http://208.180.122.191:8081/niku/wsdl/Query/ts_pending_approvals?tenantId=clarity';
var args = {Username: "jdoe", Password: "*******"};
soap.createClient(url, function(err, client) {
client.Login(args, function(err, result) {
console.log(result);
});
});
When i call console.log(client.describe()), I get the following:
{ ts_pending_approvalsQueryService:
{ ts_pending_approvalsQueryService:
{ Query: [Object],
Login: [Object],
WrappedLogin: [Object],
Logout: [Object] } } }
However, when I call login and pass the username and password, i get undefined. using SoapUI, I was able to successfully complete the request, using the following. My question is how do I simulate this in node.
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:quer="http://www.niku.com/xog/Query">
<soapenv:Header/>
<soapenv:Body>
<quer:Login>
<quer:Username>jdoe</quer:Username>
<quer:Password>******</quer:Password>
</quer:Login>
</soapenv:Body>
</soapenv:Envelope>

I was able to resolve this on my own by setting the endpoint, which gave me the expected response token: 6312078__98C024DA-25CF-441E-A47B-A84DDE2FF140
var soap = require('soap');
var url = 'http://208.180.122.191:8081/niku/wsdl/Query/ts_pending_approvals';
var args = {Username: "jdoe", Password: "*****"};
soap.createClient(url, function(err, client) {
client.setEndpoint("http://208.180.122.191:8081/niku/xog")
client.Login(args,(error,result)=>{
if (error) throw error;
console.log(result)
})
});
It is also worth noting that when you're utilizing the package and you have send additional parameters, you may also have to send headers, which map to a namespace specified in the WSDL, in addition to complex structures that require multiple parameters. I was able to figure this out after some trial and error. See working example below:
/////////////////////////////////////////////////////////////////////////////////////////////////////
// 1TS Open Timesheet
ppmRouter.get("/open_time_sheet",(req,res,next) => {
var resourceid = req.query.param_resourceid
var soap = require('soap');
var url = config.wsdlQueryPath + 'open_time_sheet';
var sheader = { Auth: {Username: config.xog_user, Password: config.password}}
var args = {
Query: {Code: "open_time_sheet"},
Filter: {
param_resourceid: resourceid
}
};
soap.createClient(url, function(err, client) {
client.addSoapHeader(sheader,"","tns","Auth");
client.setEndpoint(config.xog_url)
client.Query(args,(error,result)=>{
if (error) throw error;
console.log(result)
res.send(result)
})
});
})
