I'm having the same issue but when trying to filter the FK of an Inline Formset to customize the checkout process. In my case it seems to be because I can't get to initialize the inline properly (haven't tackled it yet) for each Cart Item. I get the same error as you, so it is probably in the "same" issue that throws that kind of error...
