When we try to export CapturedRoom getting cannotCreateNode(path: "/9EE71ED0F8D6415496A7B9F0C3671DB0321") in

We are using the RoomPlan API to capture data, which is stored in the 'CapturedRoom' variable in our code (referred to as 'finalResult'). We then attempt to save a USDZ file in the file manager. Sometimes it works, but other times, we encounter issues like the one below

Coding Error: in _IsValidPathForCreatingPrim at line 3338 of usd/stage.cpp -- Path must be an absolute path: <>
cannotCreateNode(path: "/9EE71ED0F8D6415496A7B9F0C3671DB0321")

This is that code we are using for shaving CapturedRoom data

func saveFileLocal() {
      if let finalResult {
          let fm = FileManager.default
          let documentsURL = fm.urls(for: .documentDirectory, in: .userDomainMask).first!
          //let documentsURL = URL.documentsDirectory
          let fileName = "\(UUID().uuidString).usdz"
          let fileURL = documentsURL.appendingPathComponent(fileName)
          do {
              try finalResult.export(to: fileURL)
          } catch {
              print(error)
          }
      }
  }
