Im trying to do a queryset to show date__month and total of all sale_prices

class RevenueChartListView(ListAPIView):
    queryset = Transactions.objects.annotate(month=ExtractMonth('date')).values('month').annotate(revenue=Sum('sale_price')).order_by('month')
    serializer_class = RevenueSerializer

class RevenueSerializer(serializers.ModelSerializer):
    class Meta:
        model = Transactions
        fields = ['date', 'sale_price']

However I get an error of

"Got KeyError when attempting to get a value for field `date` on serializer `RevenueSerializer`.nThe serializer field might be named incorrectly and not match any attribute or key on the `dict` instance.nOriginal exception text was: 'date'."
