I am trying to up prestashop in a docker container on an AWS EC2 instance. I use the latest docker-compose.yml file from here

.....
      - "80:80"
    user: root
    volumes:
      - ./:/var/www/html:delegated
    enter code here
.....

but when starting the container I get this error:

prestashop-git_1  | ~/html/admin-dev/themes/default ~/html

I tried to add user: root to docker-compose.yml to make sure there is no permissions issue, but it still fails.

I cloned the whole Prestashop repo:
