downloadURL throwing a exception Operation Not Permitted

[FahadG]

 The following code is throwing an exception, something about file permission with NSURLSession:

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

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

The exact error:

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=(\n Move\n), NSDestinationFilePath=/private/var/mobile/Containers/Data/Application/3E2A0069-62CB-49A5-9505-1879C7900069/tmp/o_u_k_4d1e7c7e562343f68a703ff3bcf58369_p__i_6842341270ab4113b325fa5bbc721a3f_d_.tod.gz, NSFilePath=/var/mobile/Library/Caches/com.apple.nsurlsessiond/Downloads/com.xxx.xxx/CFNetworkDownload_1qXMQT.tmp, NSUnderlyingError=0x1702540d0 {Error Domain=NSPOSIXErrorDomain Code=1 \"Operation not permitted\"}}";
}];

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):

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=(\n    Move\n), NSDestinationFilePath=/private/var/mobile/Containers/Data/Application/03757827-B45C-4CFD-9F34-DFE20371E541/tmp/Pepsi.jpg, NSFilePath=/var/mobile/Library/Caches/com.apple.nsurlsessiond/Downloads/com.-----.-----/CFNetworkDownload_usQ10T.tmp, NSUnderlyingError=0x17045a340 {Error Domain=NSPOSIXErrorDomain Code=1 \"Operation not permitted\"}}"

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:

    DBTransportDefaultConfig *transportConfiguration = [[DBTransportDefaultConfig alloc] initWithAppKey:DROPBOX_APP_KEY
                                                                                              appSecret:DROPBOX_APP_SECRET
                                                                                              userAgent:nil
                                                                                             asMemberId:nil
                                                                                          delegateQueue:nil
                                                                                 forceForegroundSession:NO
                                                                              sharedContainerIdentifier:[NSBundle mainBundle].bundleIdentifier];
    [DBClientsManager setupWithTransportConfig:transportConfiguration];

Should I open a separate issue for that on Github?

[Greg-DB]

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

[KK4iOS]

Thank's Greg, yes I did. Let's follow up there....

Please find the solution to our issue on the Github issue:

We still run our app with the Dropbox SDK obj c version 3.0.10 and have not received yet any issues from our users. Maybe you use another/later version where this problem was introduced.

I recommend, that you open a new issue directly on GitHub referring to your used Dropbox SDK version
