Cannot read properties of null (reading 'addEventListener') #11295
Description
Expected behavior
Check if canvas is 'null' before calling addListener(canvas, type,proxy).
function createProxyAndListen(chart, type, listener) {
const canvas = chart.canvas;
const proxy = helpers_segment.throttled((event)=>{
if (chart.ctx !== null) {
listener(fromNativeEvent(event, chart));
}
}, chart);
addListener(canvas, type, proxy);
return proxy;
}
Current behavior
Cannot read properties of null (reading 'addEventListener')
