@"ZZOpenOptionsCreateIfMissingKey" - code: 0, archive succeeds

[richardtop]

I'm archiving a set of files with the following code:

    NSString * zipPath = [NSString stringWithFormat:@"%@/%@", [Utility getSpeificDirectroyPath:DOCDIR], zipFileName];
    [[NSFileManager defaultManager] removeItemAtPath:zipPath error:nil];
    
    ZZArchive* newArchive = [[ZZArchive alloc] initWithURL:[NSURL fileURLWithPath: zipPath]
                                                   options:@{ZZOpenOptionsCreateIfMissingKey : @YES}
                                                     error:nil];
    
    NSMutableArray *entries = [NSMutableArray new];
    for (NSString *path in pathArray) {
        NSString *filename = [path lastPathComponent];
        ZZArchiveEntry *entry = [ZZArchiveEntry archiveEntryWithFileName: filename compress:NO dataBlock:^NSData * _Nullable(NSError * _Nullable * _Nullable error) {
            return [[NSFileManager defaultManager] contentsAtPath:path];
        }];
        [entries addObject:entry];
    }
    
    NSError *error;
    [newArchive updateEntries:[entries copy]
                        error:&error];
    
    BOOL success = (error == nil);

The archive is successful, however, in the end the error variable is not nil, but rather contains vague description:

(lldb) po error
domain: @"ZZOpenOptionsCreateIfMissingKey" - code: 0

What does this error mean?

Linking my target against ImageIO.framework solved the problem.
