privileged container nginx login issue (config)

[olaf7]

In docker-compose.yml:

image: "ghcr.io/webgiss/niolesk:unprivileged"
ports:
  - "8017:8080"

user: 180

in dockers logs:
[error] 43#43: *1 open() "/usr/share/nginx/html/login" failed (2: No such file or directory),

problem:
Using either a webbrowser or curl the container does not serve a website. Which makes sense given above error, yet is not desirable obviously.
