this is wrong. You should not change this to INT_ARRAY. Uuids are not bindable as integers

I'm open to suggestions. What should I do?

Well, the binding type should be a string array, not an int array


// Like above, but we just filter out empty strings.
$values = array_values(array_filter($values, function ($v) {
return (string) $v !== '';

this actually need to validate the pattern of uuids, otherwise postgresql will still break for invalid uuids.

But validation can already be done via constraint
The purpose here is allowing empty strings for non-required uuid fields

it cannot be done via constraint, as transforming the value is done before validating the model data (as it is necessary to build the model data).

Anyway, as I already told in PR comment, the purpose here is not validating the uuid. The purpose is just allowing empty values, otherwise an optional uuid is not working.
