在react-native中请求权限时，得到此警告（几乎是一个错误，因为应用程序此时卡住并显示黄色警告）。下面是我的代码

//MY IMPORTS

import * as ImagePicker from 'expo-image-picker';
import * as Permissions from 'expo-permissions';


//My CODE

onImageUpload = async () => {

    const {status,permissions} = await Permissions.askAsync(Permissions.CAMERA_ROLL);
    try {

        if (status === 'granted') {
            console.log("granted!!")
        }
    } catch (err) {
        console.log('onImageUpload error:' + err.message);
    }
}
