RestKit 0.2 — Error Domain=org.restkit.RestKit.ErrorDomain Code=1001 - restkit

Question

I just updated to RestKit 0.20 and I'm beating my head against my desk top trying to figure what why my Album object won't map. The response object doesn't have a keyPath — but setting it to #"" worked before.
Here is a snippet of the data coming back:
[

},
...
]
Here is my code in the App Delegate:
// restkit object manager
_objectManager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:#"http://test1.keepsayk.com"]];
[AFNetworkActivityIndicatorManager sharedManager].enabled = YES;
// restkit object store
_objectManager.managedObjectStore = [[RKManagedObjectStore alloc] initWithManagedObjectModel:[self managedObjectModel]];
[_objectManager.managedObjectStore createPersistentStoreCoordinator];
[_objectManager.managedObjectStore createManagedObjectContexts];
// setup album object
RKEntityMapping *albumEntityMapping = [RKEntityMapping mappingForEntityForName:#"KeepsaykAlbum" inManagedObjectStore:_objectManager.managedObjectStore];
albumEntityMapping.identificationAttributes = #[#"identifier"];
[albumEntityMapping addAttributeMappingsFromDictionary:#{ #"id" : #"identifier", #"title" : #"keepsaykTitle", #"description" : #"keepsaykDescription", #"date_created" : #"dateCreated", #"date_modified" : #"dateModified", #"featured_thumb_link" : #"featuredImageThumbLink", #"featured_main_link" : #"featuredImageLink", #"public" : #"isPublic", #"default_album" : #"isDefaultAlbum", #"owner_fname" : #"ownerFirstName", #"owner_lname" : #"ownerLastName", #"owner_id" : #"ownerIdentifier", #"last_media_added_date" : #"dateMediaModified", #"image_count" : #"imageCount", #"video_count" : #"videoCount", #"text_count" : #"textCount", #"audio_count" : #"audioCount", #"scrapbook" : #"scrapbookLayouts" }];
[_objectManager addResponseDescriptor:[RKResponseDescriptor responseDescriptorWithMapping:albumEntityMapping pathPattern:#"albums/display/:userID/:apiKey" keyPath:#"" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]];
I call the get method in another class — the resource path is traced in the log:
- (void)loadObjectsFromResourcePath:(NSString *)resourcePath;
{
NSLog(#"resource path: %#", resourcePath);
[RKObjectManager.sharedManager getObjectsAtPath:resourcePath parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
NSLog(#"mapping result: %#", [mappingResult array]);
[self stopLoading];
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSLog(#"error: %#", error);
[self stopLoading];
}];
}
Here is my error log:

), NSLocalizedDescription=Unable to find any mappings for the givn content, keyPath=null}

Answer 1

Set the keyPath to nil instead of #""

Answer 2

I was missing the initial "/" in my resource path.
[_objectManager addResponseDescriptor:[RKResponseDescriptor responseDescriptorWithMapping:albumEntityMapping pathPattern:#"/albums/display/:userID/:apiKey" keyPath:#"" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]];

Answer 3

If anyone still gets this error, please check your "/" so when combining the baseURL and your paths you don't end up with "www.mybase.com//blah/blah.json". Also, if you update to the latest Restkit code, as of 12/8/2012 you should get a slight fix. Blake has added code to warn with a better descriptive than 1001 during runtime.
