当我处理具有延迟作业的作业时，我遇到了utils.rb：333中的错误，该作业在同步运行时运行良好。基本上我正在做的是在我的代码中发出get请求，当我这样做时，我遇到了错误。这是遇到错误的代码行：
self.fb_friends = (JSON.parse self.fb_token.get('me/friends')).first[1] unless self.fb_friends
self是一个ruby类，self.fb_token在这里创建
OAuth2::AccessToken.new client, fb_token_string
其中client是调用OauthHelper :: client的结果，fb_token_string是来自facebook的标记字符串
这是我的堆栈跟踪：
{You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.delete
