Current behavior

I have nestjs application running in docker container. It uses HttpService which uses '@nestjs/axios' to call some service trough http. I get this error:

Error: connect ECONNREFUSED 127.0.0.1:8081

    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1159:16)

Code:

const getRequest = lastValueFrom(
      this.httpService.get("http://127.0.0.1:8081/").pipe(
        map(resp => resp.data),
      ),
    );

Expected behavior

To return the request from service.
