This error only applies to Zabbix 6.0!

Steps to reproduce:

1. Create proxy with active mode.
2. Change only proxy mode to the passive through API without specifying interface params.

{    
    "jsonrpc": "2.0",
    "method": "proxy.update",
    "params": {
        "status": "6",
        "proxyid": "11085"
    },
    "auth": "c36231fe6...",
    "id": 2
} 

    3. Open proxy setting in webui.

Result:
Error like on screenshot. API doesn't check that interface params are mandatory for passive proxy mode. API doesn't return any error.
Expected:
Error from API when trying to change proxy mode without specifying required interface parameters.
