HarmonyOS鸿蒙Next中无法获取设备唯一标识符

HarmonyOS鸿蒙Next中无法获取设备唯一标识符 参考文档，通过deviceInfo.serial获取设备唯一标识符uuid，但是实际获取为空。

接下来提示要获取以下权限：

{
 "name" : "ohos.permission.sec.ACCESS_UDID",
 "reason": "$string:uuid_access_desc",
 "usedScene": {
 "abilities": [
 "FormAbility"
 ],
 "when":"inuse"
 }
}

加上权限运行，提示以下错误，无法运行：

Install Failed: error: failed to install bundle. code:9568289 error: install failed due to grant request permissions failed.
