Hi,

Fix 17178 breaks the Teams Notification (over Workflow) for me.

[Sara]

Hi @meimler !

We already found the reason, here is the thread where we continue the discussion:

Upgraded to 2.3.0p13.cre - MS teams notification "We're sorry, this card couldn't be displayed"

The linked setup instructions do not help here. We’re getting the same error “We’re sorry, this card couldn’t be displayed” and therefore no more notifications with v2.3.0p13cee Websearch says it is something about the “adaptive card schema version”

Nice bug with p13 - preflight check is not showing any output until it is finished.
Output

2024-08-21 22:24:28 - Updating site 'home' from version 2.3.0p11.cce to 2.3.0p13.cce...

Preparing tmp directory /omd/sites/home/tmp...ATTENTION

At this point it stays then you get only the following output if this stage is finished.

  Some steps may take a long time depending on your installation.
  Please be patient.

Cleanup precompiled host and folder files
Verifying Checkmk configuration...
 01/06 Legacy check plug-ins...
 02/06 Rulesets...
 03/06 UI extensions...
 04/06 Agent based plugins...
 05/06 Autochecks...
 06/06 Deprecated .mk configuration of plugins...
Done (success)

Today i had a system where there was found a problem and you could press “c” or “d” for continue or disable package. But as you don’t saw anything you had to guess that it stays at this step und you need to press “c” and “enter” to continue.

It was very nice as it was a bigger upgrade from 2.2 to 2.3 and at such an upgrade you have every time something at the preflight check.

The pre flight check does not check everything.
What kind of issue was it?

I can reproduce the issue and raised an internal ticket. We are on it.

One more thing noticed - mkp CLI. Not adding mkp. No output at all. The mkp files are valid. It was ok with p12. That p13 has changes which broke some CLI / output functionalities.
