Hello kazuo.ito,

did You use "Unlink" or "Unlink and clear" link to unlink template?

Simply unlinking a template does not remove items created by it and therefore you get an error because interface being removed has items (from now unlinked template) using it. This is correct behavior.

On the other hand - when using "Unlink and clear" to unlink a template items created when linking to template are removed. Interface then can be removed without problems.

Hello Krists Krigers,

I tried both.
"Unlink" or "Unlink and clear" was the same result.

Fixed template linking and interface update order, commited in r47914, branch svn://svn.zabbix.com/branches/dev/ZBX-8530.

(1) I executed host.update with the following code:

{
    "hostid": "10258",
    "interfaces": [
        {
            "type": 1,
            "main": 1,
            "useip": 1,
            "ip": "192.168.3.1",
            "dns": "",
            "port": "10050"
        }
    ],
    "templates_clear ": [
        {
            "templateid": "10069"
        }
    ]
}

and received the same error.

kristsk RESOLVED - given API data has extra space in element key - "templates_clear ". Without this extra space API call works as expected.

iivs Ok, sorry then.
CLOSED.

TESTED.

Note that this works with "unlink and clear". Simple unlinking does not delete items.
