Nullable pa.Date field fails for NaT values

[bBekan-Maistra]

I have a field called confirmation_date which is nullable and has error coercion turned on. It passes the nullable check but fails on the dtype check with the following:

`
confirmation_date: pa.Date = pa.Field(nullable=True, coerce=True)

pandera.errors.SchemaError: expected series 'confirmation_date' to have type date:
failure cases:
index failure_case
0 0 NaT
1 1 NaT
2 2 NaT
3 3 NaT`

If i turn it into DateTIme, the error goes away but that's not an option since the data then get's loaded into AWS Athena where I need it to be in date form and not datetime... Shouldn't the check pass for dtype since it passed the null check?
