Unable to create a trap handler due to missing hosts/hostgroup

[mtridici]

Main question

I'm trying to create my first trap handler starting from a received trap, but I'm not able to insert the host or host group name.
The error is always the same: invalid hostname (hostid) or invalid hostgroup.
I created 2 hosts named das1 and das2 with IP addresses 1.1.1.1 and 1.1.1.2. I'm receiving correctly the traps from these IPs, but I can't create a trap handler.

Could you please help me to understand if I can fix this issue?

You may have to wait some seconds until the trapdirector has looked up the hosts matching the string that you entered.
Did you try that already?
