ruby - 删除播放列表时出现 Ruby Youtube Data API gem 错误

Question

当我执行youtube.playlists.delete请求时，我会回来

NoMethodError: undefined method `[]' for nil:NilClass
    from /Users/me/.rvm/gems/ruby-1.9.2-p320@vidyard_dashboard/gems/google-api-      client-0.4.4/lib/google/api_client/result.rb:53:in `media_type'
    from /Users/me/.rvm/gems/ruby-1.9.2-p320@vidyard_dashboard/gems/google-api-client-0.4.4/lib/google/api_client/result.rb:57:in `data?'
    from /Users/me/.rvm/gems/ruby-1.9.2-p320@vidyard_dashboard/gems/google-api-client-0.4.4/lib/google/api_client.rb:775:in `execute!'

当播放列表被删除时，该请求似乎实际上通过了，但无论出于何种原因，在返回的路上仍然会引发错误。请求的基本代码如下所示：

yt.client.execute!(
    :api_method => yt.youtube.playlists.delete, 
    :parameters => {:id => 'youtube_playlist_id'}
)
