HarmonyOS customScan.init报错1000500001？

Question

代码片段：

async onPageShow() {
  await this.requestCameraPermission();
  let options: scanBarcode.ScanOptions = {
    scanTypes: [scanCore.ScanType.ALL],
    enableMultiMode: true,
    enableAlbum: true
  }
  this.setDisplay();
  try {
    customScan.init(options);
  } catch (error) {
    hilog.error(0x0001, this.TAG, 'init fail, error: %{public}s ', JSON.stringify(error));
  }
}

运行后customScan.init报错1000500001。

由于未在module.json5添加相机权限导致if (this.userGrant)这里判断没有正确初始化XComponent，最终导致customScan.init失败，请再添加完权限后试试参考：

#module.json5
"requestPermissions":[
      {
        "name": "ohos.permission.INTERNET"
      },
      {
        "name": "ohos.permission.ACCESS_BLUETOOTH",
        "reason": "$string:access_bluetooth_reason",
        "usedScene": {
          "abilities": ["Bluetooth2Ability"]
        }
      },
      {
        "name": "ohos.permission.CAMERA",
        "reason": "$string:access_bluetooth_reason",
        "usedScene": {
          "abilities": ["EntryAbility"]
        }
      }
    ],
