Icinga2 | Elasticsearch Writer showing error "No Handler Found"

Hi Everyone,
As per my use case, I am trying to writer my performance data from icinga2 into the Elasticsearch. For that I am using Elasticsearch writer. The configuration for whom is given below. After configuring the ES writer as defined in icinga2 documentations, link for that is given below. I am getting below ES writer error in my icinga2 logs. For testing purposes I have disabled x-pack from Elasticsearch to avoid any authentication errors/handling. But still its not working. I require some assistance to troubleshoot this error. Any help will be highly appreciated. Thanks in advance.
I am using cinga = 2.13.2, icingaweb = 2.9.5 and elasticsearch = 8.3.2.

Hello @mohammadkashanzafar!

I’m afraid Icinga 2 doesn’t support ES 8+:
