Javascript 从ajax调用到ActionMailer的过程中的某个地方出现了ArgumentError

我在打ajax电话。当我按send时，我想发送一封电子邮件，但我的控制器操作中甚至没有涉及任何内容。似乎ajax调用正在出错。我在ajax调用中发送了三个字符串

老实说，我不知道是什么错了，我完全被它弄糊涂了

编辑：经过一些测试，我确信错误发生在从AJAX调用到服务器的过程中。我不知道为什么

阿贾克斯：

路线：

post 'emails/send', :to => "emails#send"

控制器操作：

def send
    email = params['email']
     Mailer.email(email['recipients'], current_user.email, email['subject'], email['content']).deliver!

     render :json => email
  end

梅勒方法：

def email(recipient, sender, subject, content)
    mail(:to => recipient, :from => sender, :body => content, :content_type => "text/html", :subject => subject)
  end

错误：

好的，我刚刚在我的Rails控制台上对Heroku进行了测试，我知道邮件程序是有效的。如果我叫它，它就行了。错误发生在AJAX调用和访问我的服务器之间。在该操作中是否有任何之前或周围的过滤器？
