How to select and pass array object to data setting of chart.js config?

I have a hidden input

<input type="hidden" id="0" value="10, 12">

and I am using

obj = [document.getElementById('0').value];

in a script tag to retrieve and use the value of the hidden input as the data array in the setting of Chart.js

const data = {
   labels: labels,
   datasets: [
      {
          backgroundColor: 'rgb(0, 255, 0)',
          data: obj,
          barThickness: 50
      }]
};

I have read Chart.js unable to display data and Treat getElementById return value as array but both those questions answers suggest converting the object to an array which I have done and it still doesn’t work.

Not able to pass array of data to chart.js in React Was a react problem and I tried adapting it but it didn’t work either.

The desired output I want can be seen in this code snippet here:

<!DOCTYPE html>
<meta charset="utf-8">
<script src="https://cdn.jsdelivr.net/npm/chart.js"></script>
<body>
    <canvas height="100px" id="myChart"></canvas>
    <input type="hidden" id="0" value="10, 12">
    <script>
        obj = [document.getElementById('0').value];
        console.log(Array.isArray(obj), obj);
        const labels = ['Type 1', 'Type 2'];
        const data = {
            labels: labels,
            datasets: [
                {
                    backgroundColor: 'rgb(0, 255, 0)',
                    data: [10,12],
                    barThickness: 50
                }]
        };
        const config = {
            type: 'bar',
            data: data
        };
        const myChart = new Chart(
            document.getElementById('myChart'),
            config
        );
    </script>
</body>

How can I achieve the same solution by somehow selecting the hidden input and passing that array as the data?

I have used console.log(); to confirm that the object is an array and that it has the correct value.

Attempts:

  1. I’ve tried surrounding the object with [] like so data: [obj], but then nothing gets displayed (probably because it’s already an array?)
  2. I’ve tried converting the array to a list as suggested here: Turn Array Into List With JavaScript but still nothing gets displayed.
  3. I’ve tried changing the values of the hidden input to be value="'10', '12'" but still nothing gets displayed.
