ios - iOS15 VisionKit：VNRectangleObservation 返回 Nil 值

Question

这是我使用 AVVisionRectangleRequest 查找矩形的代码

  let handler = VNImageRequestHandler(ciImage: ciImage, orientation: .up)
    
  let objOfAVVisionRectangleRequest = AVVisionRectangleRequest(avInputImage: ciImage, currentProcessCompletion: completion)
    
  try handler.perform([self.objOfAVVisionRectangleRequest])

在 Catch Block 中，我遇到了错误。
