TypeScript missing 'undefined' for view.container property

ArcGis version:

"@arcgis/core": "4.26.5",

According to your own post about using ArcGis with React, we should have a useEffect that unsets the views container, which seems like the way to go for freeing up the resources \ WebGL contexts created.

useEffect(() => { ... Map initialization return () => (view.container = null); }, []);

Using React with the ArcGIS API for JavaScript (esri.com)

But your Typescript definition says that view.container needs to be a HTMLDivElement

export class DOMContainer { /** * The `id` or node representing the DOM element containing the view. * * [Read more...](https://developers.arcgis.com/javascript/latest/api-reference/esri-views-DOMContainer.html#container) */ container: HTMLDivElement; ...

While you initializer allows more options:

interface DOMContainerProperties { /** * The `id` or node representing the DOM element containing the view. * * [Read more...](https://developers.arcgis.com/javascript/latest/api-reference/esri-views-DOMContainer.html#container) */ container?: HTMLDivElement | string;

The workaround is to do:

useEffect(() => { ... Map initialization return () => (view.container = null as any); }, []);

But i believe the Typescript definition should be updated, if this is the preferred way to cleanup.
