[BUG] error mounting "/workbench/attack-workbench-frontend/docker/compose/docker-compose-resources/nginx/nginx.conf" to rootfs at "/etc/nginx/nginx.conf":

When I use the pre-built image to install Workbench, I encountered the following error message.
I followed the steps from:
https://github.com/center-for-threat-informed-defense/attack-workbench-frontend/blob/main/docs/docker-compose.md

Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error mounting "/workbench/attack-workbench-frontend/docker/compose/docker-compose-resources/nginx/nginx.conf" to rootfs at "/etc/nginx/nginx.conf": create mountpoint for /etc/nginx/nginx.conf mount: cannot create subdirectories in "/var/lib/docker/overlay2/a7c81c690e068934cc07253a954772c2e9fcccd4e9bd09f447a264ad2fef030e/merged/etc/nginx/nginx.conf": not a directory: unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type

Start with docs/docker-compose.md and inspect docker/compose/docker-compose-resources/nginx/nginx.conf and its mount configuration. Reproduce the pre-built-image installation and verify whether the host path and container target are the expected file types. Done means the documented installation starts without the reported nginx.conf mount error.
