HarmonyOS connection.getAllNetsSync()在明确已经声明权限的情况下提示权限拒绝

在项目中需要使用connection.getAllNetsSync()判断当前可用网络，已经在Entry的module.json5中声明了权限ohos.permission.GET_NETWORK_INFO，但是仍然抛出异常201 - Permission denied

"name": "ohos.permission.GET_NETWORK_INFO",
"reason": "$string:reason",
"usedScene": {
  "abilities": [
  "EntryFormAbility"
  ],
  "when": "inuse"
}

/**

 * netId:
 *  101 - wifi
 *  102 - 蜂窝网
 * @returns

public  isNetworkEnable(): boolean {
  try {
    let nets = connection.getAllNetsSync();
    return nets !== undefined && nets.length > 0;
  } catch (e) {
    Log.error('isNetworkEnable error ' + JSON.stringify(e))
    return false;
  }
}
