Hello colleagues,

I think that @UI5/ui5-team-ctr-bal should take a look because the issue is not related to the form validity.

It's reproducible when isValidValue method is used in sync way and following code throws an error:

<ui5-date-picker></ui5-date-picker>
<script>
	customElements.whenDefined("ui5-date-picker").then(() => {
		const datePicker = document.querySelector("ui5-date-picker");
		datePicker.isValidValue("11/11/2018")
	});
</script>
