doctl compute firewall create gives error: "missing name"

I got a droplet: Ubuntu 16.04 (One-click-apps NodeJS 6.12.3 with monitoring)

I have setup a tag for that droplet: gmseserver All good, you can see it it the control panel.

doctl is installed via snap (version: doctl version 1.8.2-stable)

Now when I try to setup a firewall:

doctl compute firewall create --name "server-firewall" --tag-names "gmseserver" --inbound-rules "protocol:tcp,ports:22,address:0.0.0.0/0,address:::/0" --outbound-rules "protocol:icmp,address:0.0.0.0/0,address:::/0 protocol:tcp,ports:all,address:0.0.0.0/0,address:::/0 protocol:udp,ports:all,address:0.0.0.0/0,address:::/0"

Taken from: https://www.digitalocean.com/community/tutorials/how-to-secure-web-server-infrastructure-with-digitalocean-cloud-firewalls-using-doctl

I get the error:

Error: POST https://api.digitalocean.com/v2/firewalls: 422 (request "864bf621-d9a2-46d9-a652-f74b14ebd3f5") missing name

Tested to set the name as serverfirewall don’t help. Tested to use --droplet-ids <DROPLET ID> instead don’t help. Tested to remove each space and put a new space in place (in case of hidden chars) Same error on all tests.

I use Putty with SSH.

What could be the problem?
