            await self.session.commit()

            await self.session.commit()
            await self.session.refresh(statistic)

        return statistic

I double-checked the variable name, put a slash between them, and changed the query path in various ways. Nothing helped, for some reason the second variable is passed as {event_id} and not its value itself. p.s. I swapped event_id and statistic_id, and then the problems with statistic_id began. Guys, please help me, i really dont know what me do
