$ node ipnode.js

The code:
var ipcamera = require('node-hikvision-api');
// Options:
var options = {
host : '192.168.20.244',
port : '80',
user : 'admin',
pass : '1234qwer',
log : true,
};
var hikvision = new ipcamera.hikvision(options);
Please let me know what went wrong?
I was getting the same error. But after I realized that node-hikvision-api uses digest/basic authentication method. Then as you can see below, I changed the authentication method from digest to digest/basic.
If your error still persists you can use given below code for tracking alarms as I do. This code is taken from node-hikvision-api and I changed it slightly.
any patches? I have seen this api being used for node-red and it just crashes the entire service once this happens? Ideas how to fix it? my camera is set to digest/basic, onvif and cgi enabled

I get the same error, could you solve that problem?
Hello,
This issue was related to xml2js library as far as I remember. I did some adjustments to previously shared code but at this moment I could not remember. However, I can make a detailed explanation next week.
