Getting "Error in network definition: xxxx: No access points defined" when setting up wifi

I am trying to install Ubuntu Server 18.04 and I have a catch-22 problem where I need to connect to the internet to download packages (like network manager) to be able to set up my Wifi

Using this link, I am trying to modify /etc/netplan/50-cloud-init.yaml

ls /sys/class/net shows my wireless card as being wlo1

I am issuing the command sudo vi /etc/netplan/50-cloud-init.yaml and I edit the file to look like so (note,I had to visually copy this over)

#######
#######
#######
#######
#######
network:
    ethernets: {}
    wifis:
        wlo1:
            optional: true
        access-points:
            "****":
        Password: "******"
        Dhcp4: true

When I issue the command sudo netplan apply I get the following error

/etc/netplan/50-cloud-init.yaml11:21: Error in network definition: wlo1: No access points defined
                   optional:true

Putting aside the fact that Ubuntu Server should give a cleaner solution for this very common issue, this is really problematic because I have to be extra careful to never use tabs, to add a space after a colon and to just trust the vi indentation when I press ENTER

Can anyone tell me what I am doing wrong, what I should do to try to fix the problem, or at the very least what I should do to try to trouble shoot the problem
