downloadURL throwing a exception Operation Not Permitted

Question

&nbsp;The following code is throwing an exception, something about&nbsp;file permission with NSURLSession:&nbsp;[[[[DBClientsManager authorizedClient].filesRoutes downloadUrl: remotePath overwrite: true destination: destURL] setResponseBlock: ^(DBFILESMetadata *fileData, DBFILESDownloadError *downloadError, DBRequestError *requestError, NSURL *urlGot) {
&nbsp; &nbsp; if (requestError != nil) {
&nbsp; &nbsp; &nbsp; &nbsp;// I'm getting a Operation Not Permitted, something about 'Move' not allowed as app does not own the file&nbsp;

&nbsp; &nbsp; }
&nbsp; }] setProgressBlock: ^(int64_t bytesUploaded, int64_t totalBytesUploaded, int64_t totalBytesExpectedToUploaded) {
&nbsp; }];&nbsp;

The exact error:
&nbsp;
DropboxClientError[{
NSError = "Error Domain=NSCocoaErrorDomain Code=513 \"\U201cCFNetworkDownload_1qXMQT.tmp\U201d couldn\U2019t be moved because you don\U2019t have permission to access \U201ctmp\U201d.\" UserInfo={NSSourceFilePathErrorKey=/var/mobile/Library/Caches/com.apple.nsurlsessiond/Downloads/com.xxx.xxx/CFNetworkDownload_1qXMQT.tmp, NSUserStringVariant=(

}];

It sounds like you don't have permission to write to the local path specified by your "destURL". Can you check that value and confirm if you should or shouldn't have permission to it?

There was also a thread about this error message here which may be useful:

Dear Greg,
I am running exactly in the same problem. It works for us on iPad with iOS 9.3.5 and iOS 10.2 but it fails with the follwong message on a iPad Pro 12.9" with iOS 10.3 (and I made a pod update this moring to version 3.0.10):
&nbsp;
NSError = "Error Domain=NSCocoaErrorDomain Code=513 \"\U201eCFNetworkDownload_usQ10T.tmp\U201c konnte nicht bewegt werden, da du nicht \U00fcber die erforderlichen Zugriffsrechte f\U00fcr \U201etmp\U201c verf\U00fcgst.\" UserInfo={NSSourceFilePathErrorKey=/var/mobile/Library/Caches/com.apple.nsurlsessiond/Downloads/com.-----.——/CFNetworkDownload_usQ10T.tmp, NSUserStringVariant=(

&nbsp;
I implemented also the proposals with the "sharedContainerIdentifier" from your referring link (https://github.com/dropbox/dropbox-sdk-obj-c/issues/60) but I does not solve the problem:
&nbsp;
&nbsp;
&nbsp; &nbsp;&nbsp;DBTransportDefaultConfig *transportConfiguration = [[DBTransportDefaultConfig alloc] initWithAppKey:DROPBOX_APP_KEY
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; appSecret:DROPBOX_APP_SECRET

&nbsp; &nbsp; [DBClientsManager setupWithTransportConfig:transportConfiguration];
&nbsp;
Should I open a separate issue for that on Github?
&nbsp;

KK4iOS&nbsp;It looks like you did open a new issue on GitHub for this, so we'll take a look and follow up there.
