nonroot containers not working

[circletmate]

tried to add a user on host with the required data - no result.
screen with id owner in runc-config

if i change this on 0:0 owner everything will be fine. but I do not need this, I want to use the user inside the container. getting error with different startup methods.

level=error msg="container_linux.go:367: starting container process caused: setup user: cannot set uid to unmapped user in user namespace"
