Unexpected type of text node 3 error

[carlodmendoza]

Trying to draw a chart in my web app but it keeps giving this error:

Has anyone encountered the same error before?

Below is the code snippet:

` google.charts.load('current', {packages: ['corechart']}); google.charts.setOnLoadCallback(drawChart);

function drawChart() { var data = new google.visualization.DataTable(); data.addColumn('number', 'X'); data.addColumn('number', 'Dogs');

data.addRows([
    [0, 0],   [1, 10],  [2, 23],  [3, 17],  [4, 18],  [5, 9],
    [6, 11],  [7, 27],  [8, 33],  [9, 40],  [10, 32], [11, 35],
    [12, 30], [13, 40], [14, 42], [15, 47], [16, 44], [17, 48],
    [18, 52], [19, 54], [20, 42], [21, 55], [22, 56], [23, 57],
    [24, 60], [25, 50], [26, 52], [27, 51], [28, 49], [29, 53],
    [30, 55], [31, 60], [32, 61], [33, 59], [34, 62], [35, 65],
    [36, 62], [37, 58], [38, 55], [39, 61], [40, 64], [41, 65],
    [42, 63], [43, 66], [44, 67], [45, 69], [46, 69], [47, 70],
    [48, 72], [49, 68], [50, 66], [51, 65], [52, 67], [53, 70],
    [54, 71], [55, 72], [56, 73], [57, 75], [58, 70], [59, 68],
    [60, 64], [61, 60], [62, 65], [63, 67], [64, 68], [65, 69],
    [66, 70], [67, 72], [68, 75], [69, 80]
]);

var options = {
    hAxis: {
    title: 'Time'
    },
    vAxis: {
    title: 'Popularity'
    },
    backgroundColor: '#f1f8e9'
};
console.log(document.getElementById('charts_div'))
var chart = new google.visualization.LineChart(document.getElementById('charts_div'));
chart.draw(data, options);

};`

The above code works in jsfiddle but not in my web app. The console doesn't print anything as well about this error.

I have the script in the body tag of my website: <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>

Thanks for your report, Carlo. Definitely a new bug, though I am not sure why it would work sometimes, or how you might work around it. I bet there is some library also loaded in the page that overwrites the browser's implementation of Dom Nodes. I'm seeing it on some other pages, like http://yii2.kadastrcard.ru/.

Looks like dlaliberte was right that something is overriding browser's implementation of Dom Nodes. In my application I've found some obsolete code that looked like this:

function Node() {
    ...some obsolete code here...
}

After removing this code I no longer receive Unexpected type of text node 3 error and my google chart works fine again.

I have made a change that will be included in the next release (49) that avoids the potential for conflict with an overridden Node. Not sure when v49 will be released, but maybe a couple weeks.

Hello :). I would like to ask how the work is going. I`v encountered this issue in my project and I wonder how could i fix this. Any news when v49 will be released. Greetings !
