valueAsDate does not behave as per the documentation

[mrmanicou]

According to the documentation:

valueAsDate: Returns a Date normally. If something goes wrong null will be returned.

But null never gets returned. A peek into the code shows this line:

const valueDate = (ref as HTMLInputElement).valueAsDate || new Date(inputValue);

What this implies is that RHF will first try to use the native value as date function which indeed returns null if invalid Date is encountered but the new Date(inputValue) part

with an invalid date string, it returns a Date object whose toString() method returns the literal string Invalid Date.

This according to the Javascript docs.

I like the behaviour given in the docs, but the code will never give these results. Instead I'll to use setValueAs and do my own thing? Is this what others do or am I missing something?

I think i will update the doc on this, return null is probably not appropriate for input, since input will always default to string
