Difficult to use zabbix_sender

[fabregasf_CEC]

Hey Guys!
I'm facing some issues when I try to use zabbix_sender with trapper, on a single server (Centos 8). I have the programs to collect and send info about Windows Updates, but when it runs, show me an error:

ZABBIX_SENDER.EXE -c zabbix_agentd.conf -v -k zbx.win.updates.feature -o 0
Response from "192.168.1.20:10051": "processed: 0; failed: 1; total: 1; seconds spent: 0.000053"
sent: 1; skipped: 0; total: 1

I tried to change type of information, but it doesn't worked, as the image below:

I tried opening the default port 10050 on the server conf, increase the TrapperTimeout, but no solved yet.

The other script I'am triyng to use is in python. I'm passing the keys:

In Zabbix Server I have created the Trapper Items, as this example, but no ones works:

Read the documentation about using parameters carefully https://www.zabbix.com/documentation.../zabbix_sender
You have omitted the "-s " parameter.
