[Bug]: Critical error in log after upgrade to 4.0.0 - /var/lib/nginx/state/nginx-mgmt-state failed (2: No such file or directory)

Version

4.0.0

What Kubernetes platforms are you running on?

AKS Azure

Steps to reproduce

We are running Nginx Ingress Controller 4.0.0 with NAP V5, installed with Helm chart 2.0.0.

After upgrading to 4.0.0, we get the following error in the logs on each restart of the container:

2025/02/07 09:56:41 [crit] 40#40: open() "/var/lib/nginx/state/nginx-mgmt-state" failed (2: No such file or directory)

It is marked as critical (so it triggers our alerts), but we have not yet detected a consequence.

What is the consequences? And can we get rid of the error?

There is no folder /var/lib/nginx/state at all inside the container. We run read-only file system, if that is related, but /var/lib/nginx/ is writable.
