SlackAskV2 Invalid Block Format

[NDNico]

Hi folks, 

i am new with XSOAR and i try to create an approval workflow with SlackAskV2. 

Of course i prefer the default resonse type with buttons. And here's my problem. It does not work in the playbook editor.
I always get the following error, when i try to run the playbook with default settings:

Reason

The request to the Slack API failed. (url: https://www.slack.com/api/chat.postMessage) The server responded with: {'ok': False, 'error': 'invalid_blocks_format'}

In the war room on the cli, the same request works fine, without any errors.
Does anybody have an idea what i am doing wrong?
