midwayjs v3 使用了@midwayjs/upload组件 和 fliter @catch 修饰器后 或有类型冲突

启动项目直接会报格式类型错

是否有解决方案

[czy88840616]

import { Context } from '@midwayjs/web';

[mynamexjl]

（哈哈哈哈。 上面问题完美解决了哈。 能说下 egg 和。web 的 context的区别吗 ）还有个问题 typeorm synchronize 日常同步出现表已创建问题导致程序卡住问题（云 mysql 上开启会存在这个问题 本地上是不会） 我不想把 synchronize 设置 false 在通过 cli 去同步的话

1、包含关系 2、不了解，一般不会开。
