Error in timeline chart bar: <text> attribute x: Expected length, "NaN"

Third day I'm trying to get data from json without errors with google timeline chart. I thought it should worked, but i've got an error <text> attribute x: Expected length, "NaN".

There is a problem part <g><text text-anchor="middle" x="NaN" y="21.05" font-family="Arial" font-size="13" stroke="none" stroke-width="0" fill="#000000"> </text></g>

There is my chart with ajax-call to data:

var data = [];
      $.ajax({
          url: "/api/reports/6/linestatus",
          dataType: "json",
          success: function (jsonData) {
              for (var i = 0; i < jsonData.length; i++) {
                  startTime = new Date(jsonData[i].dateStart);
                  startHours = startTime.getHours();
                  startMinutes = startTime.getMinutes();
                  startSeconds = startTime.getSeconds();

                  endTime = new Date(jsonData[i].dateEnd);
                  endHours = endTime.getHours();
                  endMinutes = endTime.getMinutes();
                  endSeconds = endTime.getSeconds();
                  console.log(data);
                  data.push(
                      [jsonData[i].lineName.toString(), jsonData[i].status.toString(), new Date(0, 0, 0, startHours, startMinutes, startSeconds), new Date(0, 0, 0, endHours, endMinutes, endSeconds)]
                  );

              }
          }
      })

      dataTable.addRows(data);

My JSON data:

[{
  "lineId": 6,
  "lineName": "Line 1",
  "status": 2,
  "dateStart": "2017-08-03T15:10:20.42",
  "dateEnd": "2017-08-03T15:10:23.353"
}]

Sorry for much code. =\ Thank you.
