[Support] 上传组件触发zod校验

[RomenMark]

Describe the problem（描述问题）

@Post('/import', { description: '导入单位', middleware: [UploadMiddleware] })
async importUnit(@Files() files: Array<UploadFileInfo>) {
    return await this.unitService.importUnit([files]);
}
// 会触发zod校验，没有特定设置过校验。
@Files() files: Array<UploadFileInfo>。
// 去除Array，不会触发。但是实际是一个数组
@Files() files: UploadFileInfo

还有一点疑问，什么情况下zod会抛出Cannot read properties of undefined (reading 'length')错误，而不是一个标准的MidwayValidationError。
配置如下
validation: {
    validators: {
      zod: zod,
    },
    defaultValidator: 'zod',
  },

TypeError: Cannot read properties of undefined (reading 'length')

补充一下busboy配置

busboy: {
    mode: 'file',
    whitelist: (ctx) =>{
      if (ctx.path === '/api/unit/import') {
        return [
          '.xlsx',
        ];
      } else {
        return []
      };
    },
    mimeTypeWhiteList: {
      '.xlsx': 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
    },
    limits: {
      fileSize: 1024 * 1024 * 10,
    },
  },

你用的是zod4 ? 降级到 3 呢

[czy88840616]

Cannot read properties of undefined (reading 'length') 主要就是和 zod-validation-error ,zod 版本不一致造成的

好的，我降级试试
