Calculate Completion Estimates For All Projects

[YummyAmericano]

Hey there!

I'm looking to set up a scheduled job that calculates completion estimates for all projects. I've written a script for it, but it doesn't seem to be working properly. Surprisingly, the System Log shows no errors. Does anyone have any insights on how I can successfully perform this task using a scheduled job? I would greatly appreciate any advice or suggestions. Thank you so much!

Below is the script I've written:

var projectGR = new GlideRecord('pm_project');
projectGR.query();


while (projectGR.next()) {
    var obj = new ProjectCalculateAJAX().updateEstimateAtCompletionCost(projectGR.sys_id);
}
