I try to write 

PHAssetResource
to a local file. I got below error.

Error: Unable to locate resource <PHInternalAssetResource: 0x1740f8480> type=photo size={4288, 2848} fileSize=1896240 uti=public.jpeg filename=IMG_0001.JPG assetLocalIdentifier=8D1CB279-E377-44E0-BE7B-E37961AC33FC/L0/001

It happens for 

PHAssets
that are not on local device. I set 
isNetworkAccessAllowed
of 
PHAssetResourceRequestOptions
to true and check progress. It reports that downloading stop on 0.5 and thorw above error.


The "iCloud Photo Library" is turned on and "Optimize iPhone Storage" is checked in iOS settings.


How to fix this issue? Any suggestion?


Code:

         PHAssetResourceRequestOptions *options = [[PHAssetResourceRequestOptions alloc] init];
            options.networkAccessAllowed = YES;
            [options setProgressHandler:^(double progress) {
                NSLog(@"progress %f", progress);
            }];
       
            [[PHAssetResourceManager defaultManager] writeDataForAssetResource:exportAssetRes toFile:fileURL options:options completionHandler:^(NSError * _Nullable error) {
                isDone = YES;
                if (error) {
                    NSLog(@"Write data failure: %@", error);
                } else {
                    NSLog(@"Write data successfully.");
                }
            }];

These are iCloud server issues and they occour randomly. Best thing you can do is to retry the request.
