一、该问题的重现步骤是什么？

在biz创建了一个服务，大部分接口都有返回值，但是有些接口可以访问，打印出来的有返回值，但是前端接收不到返回值，比如list 查询列表(代码生成的，有些模块list可以访问)，select 下拉数据接口
控制台报错提示：

二、你期待的结果是什么？实际看到的又是什么？

后台返回值前端可以正常接收。但是目前前端接受到的是无法加载响应数据

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

blade 4.2.0 win

补充：使用的是2台电脑，bladex项目是在一个电脑上，是否跟gateway有关，两个项目的gateway都启动了，配置文件没有修改，端口都是80

这些出问题的接口是一直都有问题还是一会好一会不好。bladex自带的服务里的接口有没有问题，有没有出现这个问题。

两个gateway你关掉一个，保留和服务同一台机器启动的gateway。然后再访问看看结果。
