Just a wild guess:

Are $stage->id() or $foreign->id() returning an array and/or undef, perhaps,
and that's causing a hashref key that is an "empty" label?  Do you see the
"Odd number of elements" or "uninitialized value" errors?

$ perl -Mwarnings -Mstrict -MData::Dumper -e 'my $stage =3D sub { return qw=
( a
b ) }; my $foreign =3D sub { return undef }; my $query_hr =3D { stage_id =
=3D>
$stage->(), num =3D> 0, foreign_id =3D> $foreign->(), type =3D> 0 }; print
Dumper($query_hr);'
Use of uninitialized value in anonymous hash ({}) at -e line 1.
Odd number of elements in anonymous hash at -e line 1.
$VAR1 =3D {
          '' =3D> 'type',
          '0' =3D> undef,
          'b' =3D> 'num',
          'stage_id' =3D> 'a'
        };
