Comment:
I doubt this is related to the linked PR or aggregation. I believe
`Prefetch.queryset` cannot be used with `values()` queryset.
Please confirm you get a similar crash with the following queryset:
{{{#!python
queryset = PayrollLine.objects.values('code')
Order.objects.prefetch_related(
Prefetch('pay_lines', queryset=queryset, to_attr='pay_lines_values')
)
}}}
