Current behavior

With the following codes, the swagger docs don't work as expected.

--- user.dto.ts ---
export class GetUserDto {
  /**
   * The unique id of the user.
   * @example "1234"
   */
  userId: string;
}

--- user.controller.ts ---
@Controller('user')
export class UserController {
  @Post('get')
  async getUser(@Body() param: GetUserDto) {
    return { userId: 'test' };
  }
}

--- nest-cli.json ---
{
  "$schema": "https://json.schemastore.org/nest-cli",
  "collection": "@nestjs/schematics",
  "sourceRoot": "src",
  "generateOptions": {
    "spec": false
  },
  "compilerOptions": {
    "plugins": [
      {
        "name": "@nestjs/swagger",
        "options": {
          "classValidatorShim": true,
          "introspectComments": true
        }
      }
    ]
  }
}

After changing the repo to standard(non-monorepo), It works as expected.
