can't find folder /etc/nginx/certs when trying to letencrypt docker

Question

I'm very new to Linux. But i'm trying to create a docker-compose file that starts my expressjs api and my plain html website. To that i want docker-compose to renew my letsencrypt ssl certificates. When i run this i get this errors:

nginx-proxy        | dockergen.1 | 2023/12/03 16:22:38 Template error: open /etc/nginx/certs: no such file or directory

My docker-compose.yml is located in root, maybe thats the problem?

This is my docker-compose file:

version: '3'

  nginx-proxy:
    image: jwilder/nginx-proxy:alpine

    networks:
      - app-network
    restart: always

You have to create it as a volume using

nginx-proxy:
  volumes:
    - <volume>:/etc/nginx/certs:ro
    - <volume2>:/usr/share/nginx/html
nginx-letsencrypt:
  volumes:
    - <volume>:/etc/nginx/certs:ro
    - <volume2>:/usr/share/nginx/html

In order to do the challenge using and to store and read the cert from
