lineWithErrorBars about chartjs-chart-error-bars HOT 5 CLOSED

without code it is impossible to tell what is going on, since https://codepen.io/sgratzl/pen/rNGvqXb

works just fine

from chartjs-chart-error-bars.

We are using angular 12 with chart js 3.6.2 version.
For the error bars we r using version ^3.6.0. npm package, As suggested in link below:
https://www.npmjs.com/package/chartjs-chart-error-bars

We are taking canvas reference using @ViewChild decorator in Angular.
We r able to render barWithErrorBrs controller bar chrt , But when we use lineWithErrorBars , its having error as undefined context.

So please suggest if we need to do any config changes.

Continue to @mahadev-Pandhare comment, we are getting below error in console. It is happening with only lineWithErrorBars

barWithErrorBrs is working fine.

    this.resourceComboChart = new Chart(this.ctx, tempChart);
    this.resourceComboChart.update();

While doing analysis we found that DatasetController getting called twice for lineWithErrorBars, any idea why it is getting called twice? does any configuration is required to stop second call?

can you create a codesandbox or similar with a setup that is showing this error? Otherwise, I don't know how to investigate this error since it works fine in the codepen I sent before
