Comment:
Thanks for the report. I was to able to reproduce the issue without
`SubqueryArray()` and with built-in `JSONObject`:
{{{#!python
@override_settings(USE_TZ=True)
def test_group_by_crash(self):
tz = zoneinfo.ZoneInfo("Europe/Paris")
qs = Point.objects.annotate(
year=ExtractYear("start_at", tzinfo=tz),
).values("year").annotate(
baseload=Avg("value"),
json=JSONObject(
year=F("year"),
baseload=F("baseload"),
)
).values("json")
list(qs)
}}}
