HarmonyOS getCurrentLocation相关问题？

Question

geoLocationManager.getCurrentLocation({
  scenario: geoLocationManager.LocationRequestScenario.UNSET,
  maxAccuracy: 0,
  timeoutMs: 1000
});

授权成功后，打开app后第一次请求定位，必报：

startLocationBussinessError 3301200: Failed to obtain the geographical location.

再次进入就正常了，请问是什么配置错误导致的？

参考示例：

import { abilityAccessCtrl, common, Permissions, Want } from '@kit.AbilityKit';
import { geoLocationManager } from '@kit.LocationKit';

@Component
@Entry
struct LocationPage {
  permissions: Array<Permissions> = ['ohos.permission.APPROXIMATELY_LOCATION', 'ohos.permission.LOCATION'];

  getLocal() {
    const context: common.UIAbilityContext = getContext(this) as common.UIAbilityContext;
    let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
    // requestPermissionsFromUser会判断权限的授权状态来决定是否唤起弹窗
    atManager.requestPermissionsFromUser(context, this.permissions).then((data) => {
      let grantStatus: Array<number> = data.authResults;
      let length: number = grantStatus.length;
      for (let i = 0; i < length; i++) {
        if (grantStatus[i] === 0) {
          // 用户授权，可以继续访问目标操作
          const requestInfo: geoLocationManager.LocationRequest = {
            'priority': geoLocationManager.LocationRequestPriority.FIRST_FIX,
            'scenario': geoLocationManager.LocationRequestScenario.UNSET,
            'timeInterval': 1,
            'distanceInterval': 0,
            'maxAccuracy': 0
          };
          geoLocationManager.getCurrentLocation(requestInfo)
            .then((location: geoLocationManager.Location) => {
              let reverseGeocodeRequest: geoLocationManager.ReverseGeoCodeRequest = location;
              try {
                geoLocationManager.getAddressesFromLocation(reverseGeocodeRequest).then((data) => {
                  console.log('getAddressesFromLocation: ' + JSON.stringify(data));
                })
                  .catch((error: number) => {
                    console.error('promise, getAddressesFromLocation: error=' + JSON.stringify(error));
                  });
              } catch (err) {
                console.error("errCode:");
              }
            })
            .catch((err: Error) => {
              console.error(`Failed to get current location. Code is , message is ${err.message}`);
            });
        } else {
          // 用户拒绝授权
          return;
        }
      }
      // 授权成功
    }).catch((err: Error) => {
      console.error(`Failed to request permissions from user. Code is , message is ${err.message}`);
    })
  }

  build() {
    Column() {
      Button('获取位置服务授权').onClick(() => {
        this.getLocal()
      })
    }
  }
}
