How to ensure full year is entered

I have a date field on my form with a mask (00/00/0000). However, some entries are coming in without a full year, which in turn causes Power Automate to fail. Is there a way to ensure that a full year is entered? The field is not a required field.
Thank you

Hey @tverticchio,

If you need to check that the year in a date is not empty, you can get the last four digits of the date like described here, and compare them to a '0000' string.

Let me know if this helps.
