Steps to reproduce:

1. Post message to MS teams webhook
2. Recreated MS Teams integration from scratch using https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/media/msteams/media_msteams.xml?at=release%2F5.0

Result:
Sending failed: {"version":"1.1","content":{"headers":[

]},"statusCode":200,"reasonPhrase":"OK","headers":[],"trailingHeaders":[],"requestMessage":null,"isSuccessStatusCode":true}
Expected:
MS Team media should be able to send notification successfully.

We are in process to upgrade Zabbix to latest version which could take 1 month more. Until then we have to rely on Zabbix V5.0.14. Please assist.
