Using cache-manager's auto-caching responses in Nest results in empty cache content.

[Codfisher]

Describe the bug

When using CacheInterceptor, the response data of the first request is normal, but the response data of the second request becomes empty.

How to reproduce

The usage follows the documentation as described: https://docs.nestjs.com/techniques/caching#auto-caching-responses

Expected behavior

Cache content should not be empty.

Code reproduction

@UseInterceptors(CacheInterceptor)
@Controller()
export class SingleDataController {
  constructor(
    ...
  ) { }

  @TsRestHandler(singleDataContract.get, {
    validateResponses: true
  })
  async get() {
    return tsRestHandler(singleDataContract.get, async () => {
      const [error, data] = await to(this.singleDataService.get());
      if (error) {
        throw new HttpException(
          'error message',
          HttpStatus.INTERNAL_SERVER_ERROR,
        );
      }

      return {
        status: 200,
        body: data.toJSON(),
      };
    });
  }
}
