Not working against SOGo caldav server

See original GitHub issue

I cannot get this to work against a test SOGo server that we setup (Caldav applications on android work against it):

var dav = require('dav');

dav.debug.enabled = true;

var xhr = new dav.transport.Basic(
  new dav.Credentials({
    username: 'sogo1',
    password: 'xxxxxxx'
  })
);

dav.createAccount({
  server: 'https://sogo.mydomain.com/SOGo/dav/sogo1/', // This url is defined by SOGo to include the username (also tried without)
  xhr: xhr })
.then(function(account) {
  console.log(account);
  // account instanceof dav.Account
  account.calendars.forEach(function(calendar) {
    console.log('Found calendar named ' + calendar.displayName);
    // etc.
  });
})
.catch(function(err){
  console.log("ERROR", err);
});

tried with ‘iojs and nodejs (using bluebird for Promise)’

ERROR [TypeError: Cannot read property 'props' of undefined]

Dont know about the protocol yet to make sense of this … Any pointers or hints are appreciated.

Goal is to read calendar and add/edit appointments etc…
