chartjs
TypeError: Cannot read properties of null (reading 'getLabelAndValue') | TypeError: controller is null
Expected behavior
component renders normally
Current behavior
i have a barplot that is clickable to reveal a barplot below (based on where you clicked on the initial barplot). most of the time this works fine, however sometimes (and its not always..) i get the following error:
next-dev.js?3515:24 The above error occurred in the <ForwardRef(ChartComponent)> component:

React will try to recreate this component tree from scratch using the error boundary you provided,
on firefox the error is:

it seems to mainly happen when there is a lot of information on the plot. either way, is there a way for the component to fail "gracefully" rather than messing up the entire site?
Without a reproducible sample we can't help you so please add one since it is a required field in the issue template
Closing since it is not reproducible, if a reproducible sample becomes available feel free to re-open the issue again
I am facing the same error. Does anyone has the solution for the same. It is happening for the pie chart only.
@faraz-ahmad-uft can you provide any additional information? Do you have the error from your console?
