Class LaravelUi5\Core\Exceptions\InvalidSlotValueException

Thrown when the request supplies a value for a slot that is not of the slot's declared type — ?date=kaputt for a Date slot.

A 422: the caller sent it, and the caller can fix it. The value is refused rather than skipped, because falling through to the next source would answer a broken URL with the default and hide the mistake. A value that a server-side source fills with the wrong type is a different fault with a different exception ({@see InvalidSlotSourceValueException}).
