Asp.Net Core docker-compose https self signed certificate issue

I am not able to run docker-compose for an asp.net core 3 api on https with a self signed cert. I have followed the instructions on ms docs but I have given up at this point after trying everything for hours: https://learn.microsoft.com/en-us/aspnet/core/security/docker-https?view=aspnetcore-2.2

dotnet dev-certs https -ep %USERPROFILE%\.aspnet\https\aspnetapp.pfx -p { password here }
dotnet dev-certs https --trust

My docker compose is here:

version: '3.7'

networks:
  localdev:
    name: localdev
    
services:
  main-api:
    container_name: main-api
    build: 
      context: .
      dockerfile: Dockerfile
    #restart: always
    ports:
      - "5000:5000"
      - "5001:5001"
 
    depends_on:
      - db-server
    networks:
      - localdev

    volumes:
      - $USERPROFILE/.aspnet/https:/https/

    environment:
        ASPNETCORE_Kestrel__Certificates__Default__Password: "Passw0rd!"
        ASPNETCORE_Kestrel__Certificates__Default__Path: "$USERPROFILE/.aspnet/https/aspnetapp.pfx"
    
  db-server:
    image: mariadb:latest
    container_name: db-server
    environment:
      - MYSQL_ROOT_PASSWORD=Password! 
    ports: 
      - "13306:3306" 
    networks: 
      - localdev

docker-compose log is here:

If your project uses .net 6 then local path to map to volume as shown below

dotnet dev-certs https -ep %USERPROFILE%\.aspnet\https\aspnetapp.pfx -p { password here }
dotnet dev-certs https --trust

Minor change to your docker-compose file, here path will be your mounted path for the container /root/.aspnet/https/ApiHost.pfx.

environment:
  ASPNETCORE_HTTPS_PORT: 6001
  ASPNETCORE_ENVIRONMENT: Development
  ASPNETCORE_Kestrel__Certificates__Default__Path:/root/.aspnet/https/ApiHost.pfx
  ASPNETCORE_Kestrel__Certificates__Default__Password: <password>
volumes:
  - ${USERPROFILE}\.aspnet\https:/root/.aspnet/https
