req.user undefined in a cloud function when called by another cloud function

[refre5h]

Successfully reproduced this in both my env and parse-server-example, so I doubt this is an issue with our own setup. The following setup/reproduction/log are on a newly cloned parse-server-example.

A sessionToken is included when calling cloud_function_2 from cloud_function_1, but req.user is still undefined in cloud_function_2.

I've previously submitted similar (and I think related) issue #1404, and was advised that I should have revocable session enabled. But this also happens when cloud_function_1 is called by the iOS client that has it enabled [PFUser enableRevocableSessionInBackground].

Please note when cloud_function_2 is directly called by the client, req.user exists with correct token.

Environment Setup

{
    "express": "~4.11.x",
    "kerberos": "~0.0.x",
    "parse": "~1.8.0",
    "parse-server": "~2.2.2"
}

Steps to reproduce

node test_session with the following:

// test_session file

#!/usr/bin/env node

var APP_ID = process.env.APP_ID || "myAppId";
var JAVASCRIPT_KEY = process.env.JAVASCRIPT_KEY || "myJavascriptKey";
var Parse = require('parse/node');
Parse.initialize(APP_ID, JAVASCRIPT_KEY);
Parse.serverURL = process.env.SERVER_URL || "http://localhost:1337/parse";

console.log("test_session started");

var now = new Date();
var username = now.valueOf().toString();
var user = new Parse.User();
user.set("username", username);
user.set("password", "my pass");
user.set("email", username+"@example.com");

console.log("signing up user " + now.valueOf());

user.signUp().then(function(user) {
    console.log("calling cloud_function_1 with session token: " + user.getSessionToken());
    Parse.Cloud.run("cloud_function_1", null, {
        sessionToken: user.getSessionToken()
    })
}, function(error){
    console.log(error);
})

// main.js file

Parse.Cloud.define("cloud_function_1", function(req, res){
    console.log("\ncloud_function_1 was called by user: " + JSON.stringify(req.user));
    console.log("\ncalling cloud_function_2 from cloud_function_1 using sessionToken: " + req.user.getSessionToken());
    Parse.Cloud.run("cloud_function_2", null, {
        sessionToken: req.user.getSessionToken
    }).then(function(){
        res.success()
    }, function(error){
        res.error(error);
    });
})

Parse.Cloud.define("cloud_function_2", function(req, res){
    console.log("\ncloud_function_2 was called by user: " + JSON.stringify(req.user));
    var response = req.user ? req.user.getSessionToken() : "req.user in cloud_function_2 is undefined";
    res.success(response);
})

Hmm I noticed I was missing () in req.user.getSessionToken. Closing for now and will report back if I'm still having this issue.
