Sum of Integers error django.db.utils.ProgrammingError: function sum(jsonb) does not exist

Question

I'm trying to aggregate Sum() to a queryset, the fields are simple IntegerField() but this error appears.

Error:

The above exception was the direct cause of the following exception:

    ticket_public_post_processed_time = models.IntegerField(_("Totale Tempo Public Post Processed"), default=0)

Django Ver: 2.2.3

Postgres: 12

I tried with: ticket_queue=Sum(F("ticket_closed")), and ticket_queue=Sum(Cast(F("ticket_closed"), output_field=IntegerField())

But the error is still there, it's the first time it happens to me, by the way they are simple integer fields. Do you know what I can feel or where I'm wrong? Thanks for the help

Is there any way you could share the TicketHistoryAggregation model definition? It will probably help — Agate

I think there lies the issue: you are trying to Sum several fields that are declared as JSONField on your model:

ticket_store=Sum("ticket_store"),
ticket_store_managed=Sum("ticket_store_managed"),
ticket_store_total=Sum("ticket_store_total"),

You either have an issue in your model definition or in the aggregate clause
