How to handle a nullable object in the form.

I have an object that is nullable but if I try to access it using

<form.Field name="item.nullable_object"></form.Field>

<form.Field name="item.nullable_object"></form.Field>

and it's null, an error is thrown.

Think as the structure like this:

type Item = {
  nullable_item: { id: string } | null;
}

type Item = {
  nullable_item: { id: string } | null;
}
