Don't you want to cache it to avoid sending the same request for every same node ?

It could be done easily by moving this in a separate TS file

const cacheUrlExists = new Map<string, boolean>();

export async function checkIfUrlExists(url: string) {
    const cache = cacheUrlExists.get(url);
    if (cache !== undefined) return cache;

	try {
		const response = await fetch(url, { method: "HEAD" });
        cacheUrlExists.set(url, true);
		return response.ok;
	} catch {
        cacheUrlExists.set(url, false);
		return false;
	}
}

That's a good improvement, you're right. I was thinking of doing a composable as there is very similar logic in the Toolkit that I want to unify. I'll add cache. Or if you want to handle it...
