Restify在出现错误时忽略nginx头

我正在用restify+nginx创建一个服务。nginx正在添加诸如“x-xss-protection”之类的安全头

当响应返回肯定状态（如200）时，正确发送报头。但是，当我返回错误状态时，所有nginx头都会消失，请求不会通过中间件

app.get('/', (req, res, next) => {
  res.json(400, {
    test: 'test',
  });
});

app.on('restifyError', (req, res, err, cb) => {
  logger.error(err);
  return cb();
});

客户端错误的响应：
