Official integration between Zabbix and Itop not working

I have tried to do the integration (following de official documentation) between Zabbix and Itop, but they are showing the following error:

181:20210210:172252.383 [ iTop Webhook ] ERROR: Incorrect iTop ticket ID given: {EVENT.TAGS.__zbx_itop_id}
181:20210210:172357.106 [ iTop Webhook ] ERROR: Failed to parse response received from iTop.
Request status code 200. Check debug log for more information.

The official integration is: https://www.zabbix.com/br/integrations/itop
The source code: https://git.zabbix.com/projects/ZBX/...tes/media/itop

I'm using the following software:

running on xammp on a Windows Server 2016
iTop-2.7.3-664
PHP 7.1.33 (tried 5.2.6 too)

running on a Ubuntu Server
Zabbix 5.4.0alpha2 (Docker Image Official - trunk) - Already tried with Zabbix 5.2 (same error)

Configs on Media of Zabbix

The ticket is opened on Itop, but the response gives a parse error on Zabbix!

In Actions, from the Event generated:

Partial Success. Ticket opened on ITOP, but presents error and not do the ACK the event.
