Question

I have been writing an app which uses the lookback tool to get the total number of points a project had within it on a certain date. The request to pull this information looks as follows:

getPointsOn: function(date, iOIDs, callback) {
    var params    = {};
    params.find   = '{ Iteration: {$in: [' + iOIDs + ']}, PlanEstimate: { $gt: 0 }, __At: "' + date.toISOString() + '" }';
    params.fields = '[ "PlanEstimate", "Project" ]';

    Ext.Ajax.cors = true;
    Ext.Ajax.request({
        url: App.qURL,
        method: 'GET',
        params: params,
        withCredentials: true,
        success: function(response) {
            var points = {};
            Ext.Array.each(Ext.JSON.decode(response.responseText).Results, function(US) {
                if (points[US.Project] == undefined) points[US.Project] = 0;
                points[US.Project] += US.PlanEstimate;
            });
            callback(points);
        },
        failure: function() {
            console.log('Ajax Failed');
            callback({});
        }
    });
}

It returns an object with Project/Points pairs and works perfectly when 1-2 iteration ObjectIDs are passed to it. The problem is when I start requesting larger data sets. I have been getting the “Request Entity Too Large” error. I assume this is a problem with the request itself although I’m not sure how it could be “too large”. What is the likely cause of this error?

Thanks!

Large state elements, such as the values selected from a picker, should be stored with a Ext.state.LocalStorageProvider instance, rather than a Ext.state.CookieProvider. Assuming that the cookie does not need to be sent to fulfill the query request.
