I get the error Cannot read properties of undefined (reading ‘pushEvent’) when I create custom visualizations, please tell me how to fix it.

I get this error when I use the useBlinkingCells custom hook.
Here is a sample code:
import React from 'react';
import { DataFrame, PanelProps } from '@grafana/data';
import { SimpleOptions } from 'types';
import { useBlinkingCells } from 'hooks'; // custom hook
interface Props extends PanelProps<SimpleOptions> {}
export const TablePanel: React.FC<Props> = (props) => {
...
const { blinkingCells } = useBlinkingCells(
args
);
...
}
export const useBlinkingCells = (
props
) => {
const [blinkingCells, setBlinkingCells] = useState({});
...
return {blinkingCells}
}
When I remove the useBlinkingCells custom hook the error goes away, but I need the hook to work.
Thanks in advance!
