django.db.utils.NotSupportedError: FOR UPDATE cannot be applied to the nullable side of an outer join - sql

Question

I've found this error in server log. Can't replicate the problem.

django.db.utils.NotSupportedError: FOR UPDATE cannot be applied to the nullable side of an outer join
I think that it happens only on PostgreSQL database. I tried Sqlite before and it worked.
The problem is here:
match, created = Match.objects.update_or_create(
match_id=draft_match.match_id,
defaults={
field.name: getattr(
temp_match, field.name, None
) for field in Match._meta.fields if not field.name in [
'id', 'pk'
]
}
)
Is there a problem in attributes or do I must not use update_or_create and do it another way?
EDIT
In [18]: match, created = Match.objects.update_or_create(match_id=draft_match.match_id, defaults={
...: field.name: getattr(temp_match, field.name, None) for field in Match._meta.fields if
...: not field.name in ['id', 'pk','created','modified','home_team','away_team']})
returns the same error so I checked the defaults and NONE of them is ReversedForeignKey, there are only two ForeignKey but when I exclude them, it raises the same error.
