Error with null data values in Kendo line chart

[Josh]

I have a KendoChart that is set up as a line which displays gaps for missing values.  I receive the following error when I try to pass in data with null values:

SCRIPT5007: Unable to get value of the property 'value': object is null or undefined
kendo.all.js, line 72292 character 21

value = defined(item.value) && defined(item.value[field]) ? item.value[field] : item.fields[field];

My chart settings: 
$("#chart").kendoChart({
        title: {
            font: "20px sans-serif",
            weight: "bold",
            color: "#1a4a65",
            text: "Index Price Data"
        },
        legend: {
            font: "10px sans-serif",
            weight: "bold",
            color: "#1a4a65",
            position: "top"
        },
        categoryAxis: {
            type: "date",
            //baseUnits:"months",
            //field:"contractMonth",
            labels: {

                rotation: -90,
                dateFormats: {
                    days: "M/d/yyyy",
                    months: "M/d/yyyy"
                },
            },
            title: {
                font: "14px sans-serif",
                color: "#1a4a65",
                //text:"Contract Month",
            }
        },
        valueAxis: {
            labels: {
                font: "10px sans-serif",
                format: "{0:c}",
            },
            majorUnit: .2,
            title: {
                font: "14px sans-serif",
                color: "#1a4a65",
                text: "$/BBL",
            },
        },
        tooltip: {
            visible: true,
            radius: "5px",
            background: "#1a4a65",
            color: "#ffffff",
            font: "14px sans-serif",
            format: "{0:c}"
        },
        transitions: false,
        seriesDefaults: {
            type: "line",
            missingValues: "gap"
        },
    });

My series settings are set dynamically:
var chart = $("#chart").data("kendoChart");
var chartOptions = chart.options;
var categoryDates = [];
chartOptions.categoryAxis.title.text = "Price Date";
chartOptions.categoryAxis.baseUnits = "days";
chartOptions.categoryAxis.field = "priceDate";
var seriesPrices = new kendo.data.ObservableArray([]);
chartOptions.series.push([]);
chartOptions.series[0].data = seriesPrices;
chartOptions.series[0].type = "line";
chartOptions.series[0].missingValues = "gap";
chartOptions.series[0].color = "#1a4a65";
chartOptions.series[0].field = "price";
chartOptions.series[0].name = self.get('selectedIndexName');
chartOptions.categoryAxis.categories = categoryDates;
chart.redraw();

The chart displays correctly if I pass in the following data.  However, the chart does not display the empty dates after the last non-null point (8/27-8/31)

If I pass in the following data, the chart displays the entire range of dates (8/10 - 8/31), but the point for 8/26 is displayed on 8/13 and it connected to the previous points:

Please advise on how I can set up the chart to correctly display my data (all dates shown on chart, even if there is null price data for that date). 

Thank you!

Hello Josh,

Could you try to update to the latest internal build because we have fixed some major problems with the chart aggregates. Could you please tell me if you find something wrong with this build. Thank you for the understanding.

This appears to have been fixed with the update. 

Thank you
