在發出http請求時延遲作業錯誤

Question

當我在處理具有延遲作業並且同步運行時完美工作的作業時，我遇到utils.rb：333中的錯誤。基本上我在做的是在我的代碼中獲取請求，當我這樣做時，我遇到了錯誤。這是代碼，點擊錯誤的行：

self.fb_friends = (JSON.parse self.fb_token.get('me/friends')).first[1] unless self.fb_friends 

自我是一個Ruby類和self.fb_token這裏

OAuth2::AccessToken.new client, fb_token_string 

，其中客戶端調用OauthHelper ::客戶端的結果產生和fb_token_string是從Facebook

這裏記號字符串，我的堆棧跟蹤：

我遇到了同樣的錯誤

嘗試更新的oauth2到0.5.0 當我更新Omniauth到0.3.0.rc2和OAuth到0.5.0 - 問題已經解決
