getPrintHTML on Timleline results in error

[SimonF]

Hi there,
I'm getting an error on the timeline when calling getPrintHtml on a timline.
It seems that there might be a connection to "showControlsBar" whcih is set to false. Setting this to "true" results into the corresponding html.
This is reproducable in SmartClient v121p_2022-04-05_Pro and also in the latest nightly SmartClient v121p_2022-04-07_Pro in Chrome 99.0.4844.51


Code for reproduction:

isc.Button.create({
    "ID": "printButton_14",
    "click": function () {
        theTimeline.getPrintHTML({printForExport: true}, function (data) {console.log(data)});
    },
    "left": 100,
    "top": 100,
    "autoDraw": true,
    "title": "print"
});
isc.Timeline.create({
    "ID": "theTimeline",
    "width": "700",
    "autoDraw": true,
    "height": "80",
    "overflow": "hidden",
    "hideUsingDisplayNone": false,
    "hoverWidth": 200,
    "startDate": new Date(2022, 3, 4),
    "endDate": new Date(2022, 4, 1, 23, 59, 59),
    "headerLevels":
    [{
            "unit": "week"
        }, {
            "unit": "day",
            "headerWidth": 45
        }
    ],
    "showControlsBar": false,
    "showEventDescriptions": false,
    "laneFields":
    [{
            "name": "title",
            "title": "&nbsp",
            "type": "text",
            "canEdit": false,
            "escapeHTML": false,
            "shouldPrint": true,
            "editorProperties": {
                "escapeHTML": false
            }
        }
    ],
    "lanes":
    [{
            "hierarchyLevel": 0,
            "isOpen": false,
            "height": 30,
            "name": "One",
            "title": "test"
        }
    ],
    "data":
    []
})

Best regards
Simon
