Javascript：buffer.js：202 Rest call throw new TypeError（kFromErrorMsg）

Question

尝试使用javascript执行第一次Rest调用。我的代码如下：

        var https = require('https');
        var user =  '<Domain>\\*****';
        var pass = '******';

        process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

        /**
         * HOW TO Make an HTTP Call - GET
         */
        // options for GET
        var optionsget = {
            host : '**************', // here only the domain name
            // (no http/https !)
            port : 443,
            path : '/rest/api/latest/plan/dummy1/branch', // the rest of the url with parameters if needed
            method : 'GET', // do GET
            'Content-Type': 'application/json',
            Accept: 'application/json',
            auth : { 
                username: user,
                password: pass
            }   
        };

        console.info('Options prepared:');
        console.info(optionsget);
        console.info('Do the GET call');

        // do the GET request
        var reqGet = https.request(optionsget, function(res) {
            console.log("statusCode: ", res.statusCode);
            // uncomment it for header details
          console.log("headers: ", res.headers);


            res.on('data', function(d) {
                console.info('GET result:\n');
                process.stdout.write(d);
                console.info('\n\nCall completed');
            });

        });

        reqGet.end();
        reqGet.on('error', function(e) {
            console.error(e);
        }); 

但是上面会产生如下错误。请帮助理解这个问题以及如何解决它？
