Expo: Android FileSystem moveAsync or makeDirectoryAsync promise rejections

[mfoncho]

Unable to move or createDirectory these are the implementations of the some helper functions
Expo.takeSnapshotAsync works great, but moving the snapshot to the app's images directory for persistence is not possible

import { takeSnapshotAsync, FileSystem } from 'expo';

const VIEWSNAPS_DIR = FileSystem.documentDirectory + 'images/'

const timestamp = (presision=1) => Math.round((new Date()).getTime() / presision);

const ensureDirAsync = async (dir, intermediates=true) => {
    const props =  await FileSystem.getInfoAsync(dir)
    if( props.exist && props.isDirectory){
       return props;
    }
    let _ = await FileSystem.makeDirectoryAsync(dir, {intermediates})
    return await ensureDirAsync(dir, intermediates)
}

const snapViewAsync =  async (view, format='png') => {
    const dir = await ensureDirAsync(VIEWSNAPS_DIR);
    const snapshot = `${dir.uri}${timestamp()}.${format}`;
    const temp = await takeSnapshotAsync(view, {format, quality:1, result:'file'})
    let _ = await FileSystem.moveAsync({from:temp, to:snapshot});
    const info =  await FileSystem.getInfoAsync(snapshot, {md5:true})
    const type = `image/${format}`;
    return { ...info, type};
}

when snapViewAsync is called i get this error.
errror => promise rejection: Error: Directory 'file:///data/user/0/host.exp.exponent/files/ExperienceData/%2540icelye%252Fxxxx/images/' could not be created

BUGGY APP SAMPLE

im facing the same issue @mfoncho ru able to solve it

props.exist => props.exists
Following @mfoncho solution, change the above line; otherwise it will be infinite loop
