This problem may be caused by the func SiblingsProperty.detach(_:on:).

    public func detach(_ tos: [To], on database: Database) -> EventLoopFuture<Void> {
        guard let fromID = self.idValue else {...}
        let toIDs = tos.map {...}

        return Through.query(on: database)
            .filter(self.from.appending(path: \.$id) == fromID)
            .filter(self.to.appending(path: \.$id) ~~ toIDs)
            .delete()
    }

The last line which calls .delete() might be the reason why the issue happened.

The .delete() just simply build a sql and runs it, but miss invoking other lifecycle, such as middleware.

To fix this, the simplest solution is changing the .delete() to .delete(on:)

    public func detach_try(_ tos: [To], on database: Database) async throws {
        guard let fromID = self.fromId else {...}
        let toIDs = tos.map {...}
        
        try await Through.query(on: database)
                    .filter(self.from.appending(path: \.$id) == fromID)
                    .filter(self.to.appending(path: \.$id) ~~ toIDs)
                    .all().delete(on: database)
    }
