Validating Nullable Fields - donpwinston - 04-12-2018
Right now CI4 validation rules fail if the field is empty. So that they only work properly when the field is required. There should be a "nullable" rule to fix this problem. (I believe Laravel does this)
Otherwise null values should not fail validation by default.

We have the "permit_empty" rule. I think this is what you are looking for.
