Teams Webhook sending 3 alerts since 2023!

[rabusiak]

Hi
I configured Zabbix integration with Teams using webhook about 2 years ago. I was getting alerts on Teams channel without any issues untill January 1st 2023
On zabbix side I see that sending failed with information:

Sending failed: {"version":"1.1","content":{"headers":[{"key":"Content-Type","value":["text/plain; charset=utf-8"]}]},"statusCode":200,"reasonPhrase":"OK","headers" :[],"trailingHeaders":[],"requestMessage":null,"isSuccessStatusCode":tr ue}

but in reality I receive those alerts on my Teams channel... but in 3 copies. 3 posts when event is triggers and 3 when it's beeing resolved.

Any ideas what might have changed except year and how to fix this?

Found it here as a bug: [ZBX-22160] notifications to MS Teams duplicated and action failed - ZABBIX SUPPORT
There is a quick fix if someone looks for same issue here
