This article describe how to avoid the error 'One address or address group is required' in IPv4 policy.
Solution

While creating IPv4 policy based on user group or unit group, do not forget to add address object or group.
If only user group or unit group in the source field are added, the IP address is missing.
FortiGate will not be able to forward that traffic as it does not contain source IP address.
In order to avoid that error, use the address object as 'All' or specific address object in the source field.
