I have one requirement to show the aggregated task list as a webpart in any page of SP 2013 on premise, where user will see the assigned task list directly without going onto my site. After some research I found a good article here , and from that I am just trying to read the task using Work management API of SharePoint Client Object Model.

I have simply copied and pasted the code in site page and tried to console the task items but it is giving me an error in sp.workmanagement.js as below:

TypeError: this.get_context is not a function

enter image description here

I am stuck since two days, still finding no solution. If anyone can help that would be very helpful.

I have also noticed that this code does work when I put the below script code in publishing page and the page is in edit mode.

<script type="text/javascript" src="/_layouts/15/sp.workmanagement.js"></script>
<script type="text/javascript">
var context, userSessionManager ,userSession , query , myTasks ;
$(document).ready(function () {
   ExecuteOrDelayUntilScriptLoaded(function () {
       context = new SP.ClientContext.get_current();
       ExecuteOrDelayUntilScriptLoaded(function () {
           userSessionManager = new SP.WorkManagement.OM.UserOrderedSessionManager(context);
           userSession = userSessionManager.createSession();
           query = new SP.WorkManagement.OM.TaskQuery(context);
           myTasks = userSession.readTasks(query);
       }, "sp.workmanagement.js");
   }, "sp.js");

function getMyTasks() {
    context.executeQueryAsync(onGetMyTasksSuccess, onGetMyTasksFail);

// This function is executed if the above call is successful
function onGetMyTasksSuccess() {
    console.log("Successfully retrieved tasks...");
    var taskEnumerator = myTasks.getEnumerator();
    while (taskEnumerator.moveNext()) {
        var task = taskEnumerator.current;
        console.log("Task: " + task.get_id() + " - " + task.get_name());

// This function is executed if the above call fails
function onGetMyTasksFail(sender, args) {
    console.log('Failed to get tasks. Error:' + args.get_message());

So far I figured out that something of order or library reference is missing, but I am unable to get what's wrong with this.

Sorry to bother !

Found that, runtime reference of sp.js : sp.runtime.js was missing in code.

<script type="text/javascript" src="/_layouts/15/sp.runtime.js"></script>

So after I added the reference before sp.workmanagement.js, it worked ! ☺
