I am trying to run the all-in-one image within Openshift without success

Describe the solution you'd like
The image should be able to run a s non-root container, in the doc is stated that it could be run as non-root user https://docs.lowcoder.cloud/lowcoder-documentation/setup-and-run/self-hosting#run-as-non-root-user but it is not true :)

Also digging for that environment variable inside the repository doesn't bubble up anything besides the Docs
