Web scenario - error Undefined offset

[Aberad]

Hi,

Iam using since 10 years zabbix for classical infrastructure monitoring with 2 zabbix serveurs et 20 zabbix proxy install on ubuntu 16.04 with zabbix repos, and all works fined.
Since about 4 months i have created a dedicated zabbix server version 4.4 for web scenario only. I have a script that add by api automatically all of our website into zabbix, i actually have more than 10000 web scenario check activate on it.

I use template for web scenario contain 1 trigger and 1 web scenario, on the web scenario i use variable "{$WEBSITE_URL}" for the URL.. After that i created 1 host per website_url on this host i set the macro "{$WEBSITE_URL}" and affect to it the url of the website. I have a schedule task that synchronise new/deleted urls every 6 hours.

My problem occured since 2 weeks i think, the problem is that i cannot display delail of my web scenario, it impacted all of my template.

To reproduce, monitoring > web > click on the name of one webscenario :

PHP error :
