uncaught exception 'NSInternalInconsistencyException', reason: 'score is not a property of RKComment.'

[piterwilson]

I was trying out the 2.0-beta1 branch, when i came across this. It seems is not possible to get comments from a link.

What i wanted to do was something simple : pick a subreddit and try to get the comments of the stories on the subreddit's homepage.

[[RKClient sharedClient] subredditWithName:@"explainitlikeim5" completion:^void(id object, NSError* error){
        if (!error) {
            RKSubreddit *eli5 = object;
            [[RKClient sharedClient] linksInSubreddit:eli5 pagination:nil completion:^void(NSArray *collection, RKPagination *pagination, NSError *error){
                if(!error){
                    for (RKLink *link in collection) {
                        toLoad++;
                        [[RKClient sharedClient] commentsForLink:link completion:^(NSArray *comments, NSError *error) {
                            if (comments)
                            {
                                NSLog(@"Comments: %@", comments);
                            }
                            toLoad--;
                            if(toLoad == 0){
                                [self dispatchFetchComplete];
                            }
                        }];
                    }
                }else{
                    [self dispatchError:error];
                }
            }];
        }else{
            [self dispatchError:error];
        }
    }];

This crashes with
