HarmonyOS 调用相机时相机状态不可用，打印值为3

代码：

let cameraInput: camera.CameraInput | undefined = undefined
try {
  cameraInput = this.cameraManager.createCameraInput(cameraDevice)
} catch (error) {
  let err = error as BusinessError
  console.error('Failed to createCameraInput errorCode = ' + err.code);
}
if (cameraInput === undefined) {
  return undefined
}
console.log("有相机没有",JSON.stringify(cameraDevice))
cameraInput!.on('error',cameraDevice, (error: BusinessError) => {
  console.error(`Camera input error code: ${error.code}`);
})
console.log("到这里来没有", JSON.stringify(cameraInput))
await cameraInput.open()
console.log("打开相机？")

日志如下：

xxx  I     有相机没有 {}
