Bug: Date Validation Error Causes Component Crash

The component creates Date objects from location.query.start and location.query.end and calls .toISOString() on them. It fails to validate if these query parameters are valid date strings (only checking for string type). If an invalid date string is provided, new Date() returns an 'Invalid Date' object, causing .toISOString() to throw a RangeError and crash the component.

	const continuousLocationDescriptor: {end: string; start: string} | null =
	useMemo(() => {
	if (
	typeof location.query.start !== 'string' ||
	typeof location.query.end !== 'string' ||
	typeof location.query.profilerId !== 'string'
	) {
	return null;
	}
	return {
	start: new Date(location.query.start).toISOString(),
	end: new Date(location.query.end).toISOString(),
	};
	}, [location.query]);

Fix in Cursor
