Google ChartWrapper doesn't work with Histogram charts

[Nimesh]

I am following this example from Google Chart documentation.

In the project all the existing graphs are plotted using ChartWrapper, so by following example I created this chart, now all I needed to do was replace the line where new Histogram instance is created with ChartWrapper.

i.e. Replace below code with:

let chart = new google.visualization.Histogram( document.getElementById("example") ); chart.draw(data, options);

Following code:

let wrapper = new google.visualization.ChartWrapper({ chartType: "Histogram", dataTable: data, options: options, containerId: "example_chartwrapper" }); wrapper.draw();

But it doesn't work and I am getting following error:

Invalid column index 1. Should be an integer in the range [0-0].

I have created two Code pen examples replicating this issue:
