Curl Error when starting a restoration

We are taking a backup from a 16.0.4 Omnibus image and restoring to the same version deployed to EKS via Helm. When starting restoration job we are immeadiately getting error: curl: (37) Couldn’t open file followed by failure. I am using kubectl exec gitlab-toolbox -n gitlab -it -- backup-utility --restore -f file:///data/gitlab-backups/TIMESTAMP_gitlab_backup.tar to kick off the restore. Steps preceding are pretty much everything documented her: Restoring a GitLab installation | GitLab

I have a feeling I am placing the tar file in wrong location. I currently have a copy in my gitlab persistent drive and on the host machine I am running commands from. If that is the problem where should I have it? And how do I refer to the file using file:/// correctly
