Trello Automation to Slack not working

[Danni V_]

I created an automation button that posts a message on Slack. When I use the button (admin) on their board it works. However when a non-admin user on the board tries the button they get an error: 

"Slack workspace "name" is not connected.  

I see that Slack is Powered up on their board.  

I'm not sure how to solve this issue.

Hi @Danni V_ 

I think this is because of the way automations work.

If you create an automation, such as "When a green label is added to a card, post the comment "This task is done" to slack channel #test"...This automation is run from the person who created the automation, so if you created it, it would show in the log that it was run by you, even if someone else added the green label

Buttons on the other hand run on behalf of whoever clicked the button, so I think this is seeing that when Steve clicks the button, steve's Trello account is not connected to a slack account in automation.

A workaround is to have your button automation there to trigger another automation:
The example below has a bonus of you being able to send ad-hoc messages to the slack channel also...

Button automation:

Note: replace the text after @slack with your own

Then do an automation rule as below:

Note: replace the slack channel name and workspace with your own
