Unable to access back office on fresh docker creation

Hello,

I launched the docker demo and the home page works. When I connect to /admin, it tells me I have to delete /install and rename /admin. I deleted /install and that cleared that message, but when I try to rename /admin I get a 500 error.

Say I rename it to /admin123 and I try to browse to /admin123

Oops! An Error Occurred
The server returned a "500 Internal Server Error".

Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.

below is the docker-compose-yaml I used - this is all I've done so far

services:
  mysql:
    container_name: some-mysql
    image: mysql:5.7
    restart: unless-stopped
    ports:
      - 3306:3306
    environment:
      MYSQL_ROOT_PASSWORD: admin
      MYSQL_DATABASE: prestashop
    networks:
      - prestashop_network
  prestashop:
    container_name: prestashop
    image: prestashop/prestashop:latest
    restart: unless-stopped
    depends_on:
      - mysql
    ports:
      - 8080:80
    environment:
      DB_SERVER: some-mysql
      DB_NAME: prestashop
      DB_USER: root
      DB_PASSWD: admin
      PS_INSTALL_AUTO: 1
      PS_DOMAIN: localhost:8080
      ADMIN_MAIL: demo@presashop.com
      ADMIN_PASSWD: prestashop_demo_1234
    networks:
      - prestashop_network
networks:
    prestashop_network:

The docker logs just show the request, but i'll try to turn on verbose and catch the 500 error message

172.19.0.1 - - [13/Nov/2025:22:46:21 +0000] "GET /admin123/ HTTP/1.1" 500 1205 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:146.0) Gecko/20100101 Firefox/146.0"

What is the secret sauce to getting into the /admin interface using the docker demo? I'll start trying to debug, but just thought I'd log a ticket since it seems the happy path might be broken.

Start by reproducing the issue with the provided docker-compose YAML, removing /install, renaming /admin, and requesting /admin123. Inspect the container logs with verbose error reporting enabled; done means the renamed back-office URL loads without a 500 error.
