Can’t add 0.0.0.0/0 as source or destination to a firewall rule on Cisco Meraki Firewall

You might get the following error message when adding a firewall rule with 0.0.0.0/0 as source or destination

The reason is to use different predefined keyword instead of using 0.0.0.0/0.

instead using 0.0.0.0/0 you need to use Any keyword
