Bitwarden fails to start

I am following this tutorial: How to Install Bitwarden on Ubuntu 20.04 - HostnExtra. I got to step 6. I run into this error though:
ERROR: .FileNotFoundError: [Errno 2] No such file or directory: ‘/home/bitwarden/bwdata/docker/docker-comp
ose.yml’
ERROR: .FileNotFoundError: [Errno 2] No such file or directory: ‘/home/bitwarden/bwdata/docker/docker-comp
ose.yml’
How do I resolve this?

Can anyone please assist me?
