TypeError: 'Q' object is not subscriptable

[SumJest]

Using a combined filter, in one of the expressions of which negation is used, the exception appears:

TypeError: 'Q' object is not subscriptable

Expression that called exception:

ForeignProduct.objects.filter(Q(id=86) & ~Q(marketplace_user_id=1))

The model code is quite large, because there is inheritance. But if it is needed, I will send it. In the project, I got around this bug by using the exclude method for expressions with negation, but it isn't solution.

Steps to Reproduce

Just filter some EavQuerySet with more than 1 expression, one of which is negated.
