Error 513 when downloading a file.

[AaronMcGranaghan]

Hello, hoping someone can help with an issue I've recently come across. I can't be sure when it started happening, but when I try to download a file I get error 513:

DropboxClientError[{
    NSError = "Error Domain=NSCocoaErrorDomain Code=513 \"\U201cCFNetworkDownload_KWoAqe.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/BUNLE_ID/CFNetworkDownload_KWoAqe.tmp, NSUserStringVariant=(\n    Move\n), NSDestinationFilePath=/private/var/mobile/Containers/Data/Application/220F0D18-CF5B-4FEE-8248-B0BEF2F6517E/tmp/7B749750-D583-4D3C-AEED-FD1916439C82, NSFilePath=/var/mobile/Library/Caches/com.apple.nsurlsessiond/Downloads/BUNDLE_ID/CFNetworkDownload_KWoAqe.tmp, NSUnderlyingError=0x280384240 {Error Domain=NSPOSIXErrorDomain Code=1 \"Operation not permitted\"}}";

The code I'm using has worked fine for a long time and hasn't been changed:

NSString *tmpDir = NSTemporaryDirectory();
NSURL *destURL = [NSURL fileURLWithPath:[tmpDir stringByAppendingPathComponent:[dropboxPath lastPathComponent]]];
[[[[DBClientsManager  authorizedClient].filesRoutes downloadUrl:dropboxPath overwrite:YES destination:destURL] setResponseBlock:^(DBFILESFileMetadata *result, DBFILESDownloadError *routeError, DBRequestError *networkError, NSURL *destination) { ...

The odd thing is, this error only occurs on some of my devices, not all of them.

I'm using iOS (13.31) and ObjectiveDropboxOfficial (3.11.2).

A 513 Cocoa error is NSFileWriteNoPermissionError, indicating a local filesystem permission issue. There have been a few similar issues like this in the past with more information and potential solutions that may be helpful:

• 513 error when running api v 2 on two different devices #60
• DBDownloadUrlTask permission issue 513 under iOS 10.3 #125
• iOS 11.2.2 cant download files from Dropbox in last (3.4.0) ObjectiveDropboxOfficial SDK #209

Also, as John pointed out, 'BUNLE_ID' doesn't seem to be correct. Is that actually in the path in the output, or is that a typo from redacting your bundle ID for this post?

Yes, that was a typo in my redaction. All paths are valid and correct. I'll check out some of the other issues and see if any of those solutions help.

Thanks.

Using forceForegroundSession seems to have fixed the problem. Thanks for the pointers.
