Javascript 快速请求已中止

我正在使用Express.js实现我的后端。我经常犯错误。我不知道为什么

我将源代码放到AWS Elastic Beanstalk并设置ELB。如果此错误触发更多次，将使所有用户无法连接到服务器。我总是重启Beanstalk实例来解决这个问题。但我不知道什么时候会触发这个错误。所以请帮我修一下

非常感谢

当客户端在读取正文完成之前中止请求时，将发生此错误。status属性设置为400，type属性设置为'request.aborted'。请输入安装快速代码

请输入密码！！！！阅读multer js模块，我认为它对于发送请求正文数据很有用。更新一些源代码查看此链接：我发现在发送json时会触发此错误。json大小为15000B到2xxxxB。只有这个api有这个问题。其他api工作正常。这不是答案！请键入它，如注释。

app.use((req, res, next) => {
  logger.info(`marker 1, ${req.header('Content-Type')}, ${req.header('Content-Length')}`)
  next()
})

app.use(express.json({
  type: 'application/json',
  limit: '50mb',
  strict: false,
  verify: (req, res, buf, encoding) => {
    logger.info(`marker 2, ${req.body.length}`)
  }
}));
app.use(express.urlencoded({ extended: false }));
app.use(express.static(path.join(__dirname, 'public')));

// catch 404 and forward to error handler
app.use(function(e, req, res, next) {
  // set locals, only providing error in development
  logger.error(e);
  const err = SQError.wrapError(e);
  
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.httpCode || 500);
  var response = req.body.params ? req.body : {};
  logger.error(err, req.app.get('env') === 'development' ? {method: req.body.method || ""} : {});
  if(response.params) 
    response.params.error = err.toJson()
  else 
    response = { error : err.toJson() }
  res.json(response);
});
