使用@nestjsx/crud+TypeORM+PostgreSQL时遇req.parsed解构为空错误

我正尝试按照官方文档搭建基础API端点，已成功通过Swagger生成接口页面，但访问http://localhost:3000/app-user/1098时出现如下错误：

ERROR [ExceptionsHandler] Cannot destructure property 'parsed' of 'req' as it is null.
TypeError: Cannot destructure property 'parsed' of 'req' as it is null.
    at AppUserService.getMany (C:\tmp\crud-demo\node_modules\@nestjsx\crud-typeorm\src\typeorm-crud.service.ts:99:13)
    at AppUserController.getManyBase (C:\tmp\crud-demo\node_modules\@nestjsx\crud\src\crud\crud-routes.factory.ts:215:27)
    at C:\tmp\crud-demo\node_modules\@nestjs\core\router\router-execution-context.js:38:29

使用的依赖版本如下：

{
    "@nestjs/common": "^10.0.0",
    "@nestjs/core": "^10.0.0",   
    "@nestjs/typeorm": "^10.0.0",
    "@nestjsx/crud": "^5.0.0-alpha.3",
    "@nestjsx/crud-request": "^5.0.0-alpha.3",
    "@nestjsx/crud-typeorm": "^5.0.0-alpha.3",
    "pg": "^8.11.3",
    "typeorm": "^0.3.17"
}

这个错误源于@nestjsx/crud v5 alpha版本与NestJS v10的兼容性问题，核心是crud模块无法正确处理NestJS v10的请求对象结构，可通过以下方式修复：

• 降级NestJS版本：将@nestjs/common、@nestjs/core、@nestjs/typeorm降级到v9.x版本（如^9.0.0），v5版本的crud原本就是为NestJS v9设计的，这是最直接的解决办法。
• 注册Crud请求拦截器：在对应功能模块中全局注册CrudRequestInterceptor，确保请求对象被正确解析：

  import { Module } from '@nestjs/common';
  import { APP_INTERCEPTOR } from '@nestjs/core';
  import { CrudRequestInterceptor } from '@nestjsx/crud';
  import { AppUserController } from './app-user.controller';
  import { AppUserService } from './app-user.service';
  
  @Module({
    controllers: [AppUserController],
    providers: [
      AppUserService,
      {
        provide: APP_INTERCEPTOR,
        useClass: CrudRequestInterceptor,
      },
    ],
  })
  export class AppUserModule {}
  

• 检查路由配置：访问/app-user/1098是单条数据查询，却触发了getMany方法，可能是控制器的@Crud装饰器配置有误，确保正确绑定实体模型：

  import { Crud, CrudController } from '@nestjsx/crud';
  import { AppUser } from './app-user.entity';
  import { AppUserService } from './app-user.service';
  
  @Crud({
    model: {
      type: AppUser,
    },
  })
  export class AppUserController implements CrudController<AppUser> {
    constructor(public service: AppUserService) {}
  }
