UCWA Lync authentication - 500 web ticket is invalid - node.js

Question

I'm trying to create a simple client for Lync using Nodejs.
Base on http://ucwa.lync.com/documentation/KeyTasks-CreateApplication I've made someting like this.
It works until last step #9 when I should register my app with UCWA. Server responds with code 500 and silly explanation
There is a problem with the resource you are looking for, and it cannot be displayed
And headers
x-ms-diagnostics': '28032;source="mysource";reason="The web ticket is invalid."'
var http = require('request-promise');
var lync = {};
lync.setup = function(email, password){
var self = this;
var hostname = email.split('#');
this.username = email;
//discover urls
return http.get('http://lyncdiscover.'+hostname[1])
.then(function(d) {
var parsed = JSON.parse(d);
self.urls = {
self: parsed._links.self.href,
user: parsed._links.user.href,
xframe: parsed._links.xframe.href
};
return http.get(self.urls.user);
}).catch(function(err){
if(err.statusCode == 401){
var toParse = err.response.headers['www-authenticate'];
var Oauth = toParse.match(/https:\/\/[\d\w\./_-]*/i)[0];
var loginPost = {
grant_type: 'password',
username: email,
password: password
};
return http.post(Oauth, {form:loginPost});
}
return false
}).then(function(data){
var parsed = JSON.parse(data);
//setup authorization
http = http.defaults({
headers: {Authorization: parsed.token_type + ' ' + parsed.access_token}
});
//console.log(self.urls.user);
//console.log('Authorization:'+ parsed.token_type + ' ' + parsed.access_token);
return http.get(self.urls.user);
}).then(function(data){
var parsed = JSON.parse(data);
self.urls.applications = parsed._links.applications.href;
var registerApp = {
culture : "en-us",
endpointId : "2d9dc28d-4673-4035-825c-feb64be28e4e",
userAgent : "Test"
};
var r = "{'userAgent': 'NodeJs', 'endpointId' : '2d9dc28d-4673-4035-825c-feb64be28e4e', 'culture': 'en-US'}";
return http.post(self.urls.applications, {body: registerApp, json:true});
})
.then(function(data){
console.log(data);
})
.catch(function(err){
console.log(err);
return false;
});
};
//run app
lync.setup('login#domain.com', 'password').then(function(ret){
});
One key point here. It's not my server. I just have an account over there and I can login with official Lync client or Pidgin plugin.
Are there some extra steps to "allow" my app to work with UCWA?

I can easily authorize using Oauth. I'm receiving authorization token so I'm logged in.
I'm receiving json similar to
"_links":{
"self":{"href":"link"},
"applications":{"href":"i need this"},
"xframe":{"href":"link"}
} }
Now. I need to "register my application" doing POST.
In this last step I get 500 code response.
I hope It's not related with that #Matthew Proctor said..
becouse I cannot simple administrate the server

Answer 1

Thank you #ShelbyZ
You were right, it was split-domain scenario. Now authorization works, and I can register my app. Also example for future generations
var http = require('request-promise');
var lync = {};
lync._authorize = function(){
var self = this;
var orgDomain = self.urls.user.match(/https:\/\/([\w\d\.]+)/i)[0];
//console.log(orgDomain);
http.get(self.urls.user).catch(function(err){
if(err.statusCode == 401){
var toParse = err.response.headers['www-authenticate'];
var Oauth = toParse.match(/https:\/\/[\d\w\./_-]+/i)[0];
var loginPost = {
grant_type: 'password',
username: self.username,
password: self.password
};
return http.post(Oauth, {form:loginPost});
}
}).then(function(data){
if(data) {
var parsed = JSON.parse(data);
//setup authorization
http = http.defaults({
headers: {Authorization: parsed.token_type + ' ' + parsed.access_token}
});
return http.get(self.urls.user);
}
}).then(function(data){
//check for split-domain scenario
var parsed = JSON.parse(data);
var domain = parsed._links.self.href.match(/https:\/\/([\w\d\.]+)/i)[0];
console.log('[1] '+orgDomain);
console.log('[2] '+domain);
if(domain!== orgDomain){
//split domain scenario
self.urls.user = self.urls.user.replace(orgDomain, domain);
http = http.defaults({
headers: {Authorization: null}
});
self._authorize();
} else { //create app
var parsed = JSON.parse(data);
self.urls.applications = parsed._links.applications.href;
var registerApp = {
culture : "en-us",
endpointId : "2d9dc28d-4673-4035-825c-feb64be28e4e",
userAgent : "NodeJs client"
};
return http.post(self.urls.applications, {body: registerApp, json:true});
}
}).then(function(app){
console.log(app);
});
};
lync.setup = function(email, password){
var self = this;
var hostname = email.split('#');
this.username = email;
this.password = password;
//discover urls
return http.get('http://lyncdiscover.'+hostname[1])
.then(function(d) {
var parsed = JSON.parse(d);
self.urls = {
self: parsed._links.self.href,
user: parsed._links.user.href,
xframe: parsed._links.xframe.href
};
return self._authorize();
});
};
//run app
lync.setup('username#domain.com', 'password');

I was getting the same error before I added my test domain to the list of Allowed Domains.
This can be updated via PowerShell, full details below:
Enabling UCWA and Configuring Allowed Domains
I've had clients see similar errors when running my code from http://localhost/, their fix was to test their code on a FQDN (ie http://testmyucwacode.mydomain.com/).
