external volume "docdoku-plm-server-volume" not found

[mgeminn]

I have installed according to "https://github.com/docdoku/docdoku-plm-docker" on ubuntu desktopn 22.04 LTS.

All pulling was succesfullly finished, but at the end the message "external volume "docdoku-plm-server-volume" not found" rised up.

Then I mounted an external drive ( exfat, for it has 20TB ) in fstab:
UUID=7FED-F828 /home/mgeminn/docdoku-plm-docker/data/docdoku-plm-server-volume exfat defaults 0 0

Still the same message.

What should I do to solve?

Thanks in advance.
