Generic parameter 'Parameters' could not be inferred

hi guys, I try to write a ApiRequest class to handle common request settings and response data, here is a delete function I wrote below:

public static func delete<Parameters: Encodable>(_ convertible: URLConvertible, parameters: Parameters? = nil, success: @escaping (Data?)->Void, failure: @escaping (ApiError)->Void) {
    debugPrint("ApiRequest.delete->")
    debugPrint(convertible)
    debugPrint("parameter-> \(parameters)")
    AF.request(convertible, method: .delete, parameters: parameters).response{ response in
      handleResponse(response, success: success, failure: failure)
    }
  }

I used an optional type-inferred parameter here. I got "Generic parameter 'Parameters' could not be inferred" error when I call this function without parameters:

ApiRequest.delete("\(WorkoutApi.routine_delete.rawValue)/\(id)",success: {response in
      let index = self.routineList.firstIndex(where: { routine in
        routine.id == id
      })
      if index != nil {
        withAnimation(.spring()){
          self.routineList.remove(at: index!)
        }
      }
    }, failure: {error in
       
    })

Somebody please help me!! How can I get this code right.Waiting online
