Comment:
Setting `Case(output_field)` doesn't issue a `CAST`.
[https://docs.djangoproject.com/en/4.2/ref/models/database-functions/#cast
Using a proper] `Cast` should address your issue.
{{{#!python
Cast(Case(
When(
id__isnull=True,
then=F("data__test")
),
default=F("data__test"),
), IntegerField(null=True))
}}}
