DeckGlLayer & TypeScript errors

[artello73]

Almost broke my head on trying to find a solution for type mismatch on DeckGlLayer

<DeckGlLayer
	type={ArcLayer}
	data={data}
	bind:hovered
	getSourcePosition={sourceHandler}
	getTargetPosition={targetHandler}
        getSourceColor={heatColorGenerator}
	getTargetColor={heatColorGenerator}
	autoHighlight={true}
	highlightColor={[30, 255, 30]}
	getWidth={5}
	getHeight={0.25}
	getTilt={tiltHandler}
>

For some reason Typescript expects data: string[], while it's completely useless to have an array of string here.
in the DeckGlLayer example https://svelte-maplibre.vercel.app/examples/deckgl-arcs data is an array of objects too.
Am I missing something? Of course everything works, just typescript is whining a bit :)

so if you look at the source for DeckGlLayer, you'll see it's using a generic that just expects an array of some type, and this helps it to inform the typing on the event handlers which would use a singleton of that type.

What is data in your example? If it's expecting string[] that seems to imply either that your data is a single string or that Typescript is doing something unexpected.

Yes, I saw that data is declared as $$Generic in source code. In my case its a Array<LinkInfo>

type LinkInfo = {
	name: string;
	a_site: string;
	b_site: string;
	comments: string;
	distance: number;
	heat_value: number;
	a_geo: [number, number];
	b_geo: [number, number];
};

I'll give a try to setup a clean project and check if this is the something wrong with my repo ...
