Date Range Picker - Invalid Date when User opens and closes Calendar without picking date despite

[safe crescent]

Hello, I have a form that uses a date range picker. When a user opens and closes the calendar without picking a date, and the form submits, with that field technically "empty", the values that are passed along to submit are "invalid date" I was wondering how to overcome this. The form is considered required so I'm not sure how this could be possible....

if you want to force the form to require two valid dates you can add a validate function

for example, checking if some date is null:
