TypeError after unmounting chart

I have a <Line> chart in my React app. Since I updated chart.js to v4.0.1, I get the following error when I unmount my chart:

Uncaught TypeError: Cannot set properties of null (setting '_setStyle')
    at chartjs-plugin-streaming.esm.js:787:1
    at each (helpers.core.ts:149:1)
    at Chart.update (chartjs-plugin-streaming.esm.js:785:1)
    at chartjs-plugin-streaming.esm.js:601:1
    at callback (helpers.core.ts:109:1)
    at chartjs-plugin-streaming.esm.js:68:1

This error is triggered repeatedly and infinitely. It seems that some kind of timer has not been cleared.

Here’s my code:

<Line
  data={{datasets}}
  options={{
    scales: {
      x: {
        display: false,
        realtime: {
          delay: 1000,
          onRefresh: (chart) => {
            const x = Date.now();
            const y = getY();
            chart.data.datasets.forEach((dataset, i) => {
              dataset.data.push({
                x,
                y: y[i]
              });
            });
          }
        },
        type: 'realtime'
      },
      y: yOptions
    }
  }} />

@Dola97 If you’re still interested, I forked the project and fixed this issue. I also bumped all dependencies versions.

Yes, that’s obviously what I did. But that’s not sustainable.
