Steps to reproduce:

1. Post message to MS teams webhook

Result:

Action fail with error:

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":true}

 

Messages on MS Teams are posted but duplicated or triplicated.

Issue started yesterday 3 January 2023, probably due to a change on MS Teams side

 

Expected:
Messages posted only 1 time and action that is not failing
