AI Summary: The issue is a permission problem when the Next.js application running inside a Docker container attempts to create a cache directory for image optimization. The proposed solution of adding a `mkdir` command to the Dockerfile before switching users did not resolve the problem. The task requires debugging the Dockerfile and Docker Compose configuration to identify why the user permissions are still incorrect, and then correctly setting the permissions so the application can create the necessary directory.
