Steps to reproduce:

1. Create a new template.
2. Add a new Item with key "icmpping[8.8.8.8]" to the template.
3. Create a new host without an interface.
4. Add the template to the host.

Result:
Cannot find host interface on "New Host" for item key "icmpping[8.8.8.8]".
Expected:

If we add a dummy interface, the template is added successfully, and starts pinging 8.8.8.8 from the Zabbix server.

Ping works.
