ios版本15.5，微信版本8.0.25，已经开启了微信定位，但是在调用wx.getLocation一直返回失败

代码片段

获取位置
authPowerSetting是wx.getSetting返回的结果
fetchLocation: async function () {
    const sysInfo = await wx.getSystemInfoSync();
    const locationEnabled = sysInfo['locationEnabled'];
    wx.getLocation({
      type: 'wgs84',
      success (res) {
        wx.hideLoading();
        if (res.errMsg == "getLocation:ok") {
          console.log(res)
        } else {
          try {
            if (!locationEnabled) {
              wx.showToast({
                title: '请手动开启手机系统定位功能',
                icon: 'none',
                duration: 2000,
              });
              return;
            }
          } catch (error) {};
          try {
            let authPowerSetting = _this.data.authPowerSetting;
            if (!authPowerSetting || !authPowerSetting.getUserLocation) {
              wx.showToast({
                title: '请在小程序右上角“...”-“设置”开起定位功能',
                icon: 'none',
                duration: 2000,
              });
              return;
            }
          } catch (error) {};
        }
        console.log(res)
      },
      fail(err) {
        wx.hideLoading();
        try {
          if (!locationEnabled) {
            wx.showToast({
              title: '请手动开启手机系统定位功能',
              icon: 'none',
              duration: 2000,
