java.io.IOException: Attempted read from closed stream. MS changed the Teams response

[Eric-Maddox]

I found the issue in logsteamcity-server.log on the build server.
java.io.IOException: Attempted read from closed stream.
at msteamsnotifications.MsTeamsNotificationImpl.postViaWebHook(MsTeamsNotificationImpl.java:184)

Microsoft made a change that broke things for many people.
The change in the Webhook is documented here: MicrosoftDocs/msteams-docs#7830

[Eric-Maddox]

The closed stream error happens because we get a 400 from the server and then try to read the results back twice, once as an error message and again as content. The stream can only be read once.

[Eric-Maddox]

MsTeamsNotification failed : returned error Bad payload received by generic incoming webhook.

The 400 error is because the notification is sending JSON, but sending the content type header application/x-www-form-urlencoded
