@jentrup346734 Looks like the json format you are using is for old connector format. Since you are using a workflow you should be following the json format for the adative cards : just below the curl / powershell section, here.

The "Send_each_adaptive_card" of the workflow requires the "attachments" parts filled as an adaptive card, which is not present in your original json and hence the error.

@vivekk0903 Yes that is accurate, however we still need the documentation updated as the documentation is incorrect when using the new workflows.

@jentrup346734 - We have shared the feedback with engineering team to update the documentation with examples for workflows.
