waitForQueueAsync throws Sys.ArgumentNullException Value cannot be null. Parameter name: clientObject

Question

I'm trying to update a resource (using JSOM) by adding a calendar exception, but I'm getting a Sys.ArgumentNullException when running the request on the server

Here's a piece of my code:

// Initialize the current client context.
projContext = PS.ProjectContext.get_current();

// Get the collection of enterprise resources.
resources = projContext.get_enterpriseResources();

// Register the request for information that you want to run on the server.
projContext.load(resources, "Include(Id, Name, ResourceCalendarExceptions, IsGeneric)");

// Run the request on the server.
projContext.executeQueryAsync(UpdateResources, QueryFailed);

function UpdateResources(response)
{
    // Initialize a CalendarExceptionCreationInformation object and specify properties.
    var creationInfo = new PS.CalendarExceptionCreationInformation();
    creationInfo.set_name("Vacations");

    // Specify properties.
    creationInfo.set_start("2013-09-20 00:00:00.000");
    creationInfo.set_start("2013-09-21 00:00:00.000");

    var resourceId = "XXX";
    var resource = resources.getById(resourceId);

    // Add the calendar exception to the collection.
    resource.get_resourceCalendarExceptions().add(creationInfo);

    // Submit the request to update the collection on the server
    var updateJob = resources.update();
    projContext.waitForQueueAsync(updateJob, 10, IterateThroughResources);
}

Fixed it!

I used executeQueryAsync instead of waitForQueueAsync and also enabled administrative permissions.

Hope it helps!
