ruby-on-rails - NoMethodError（nil的未定义方法`id'：NilClass） - Thinbug

当我通过cURL请求在Redmine上创建票证时，我收到此错误。我的cURL正在成功创建票证，但它也返回错误，我无法理解为什么会这样。

这是我得到的错误：

NoMethodError (undefined method `id' for nil:NilClass):
lib/redmine/hook.rb:61:in `block (2 levels) in call_hook'

这是控制器代码

def create
call_hook(:controller_issues_new_before_save, { :params => params, :issue => @issue })
@issue.save_attachments(params[:attachments] || (params[:issue] && params[:issue][:uploads]))
if @issue.save
  call_hook(:controller_issues_new_after_save, { :params => params, :issue => @issue})
  respond_to do |format|
    format.html {
      render_attachment_warning_if_needed(@issue)
      flash[:notice] = l(:notice_issue_successful_create, :id => view_context.link_to("##{@issue.id}", issue_path(@issue), :title => @issue.subject))
      if params[:continue]
        attrs = {:tracker_id => @issue.tracker, :parent_issue_id => @issue.parent_issue_id}.reject {|k,v| v.nil?}
        redirect_to new_project_issue_path(@issue.project, :issue => attrs)
      else
        redirect_to issue_path(@issue)
      end
    }
    format.api  { render :action => 'show', :status => :created, :location => issue_url(@issue) }
  end
  return
else
  respond_to do |format|
    format.html { render :action => 'new' }
    format.api  { render_validation_errors(@issue) }
  end
end
end

这是调用钩子的代码

def call_hook(hook, context={})
    [].tap do |response|
      hls = hook_listeners(hook)
      if hls.any?
        hls.each {|listener| response << listener.send(hook, context)}
      end
    end
  end
