How to create automation that doesn't allow the transition of cards in the workflow?

Question

Guys, I'm trying to create an automation where when placing a Flag in an issue, it cannot be changed in the workflow until the Flag is removed. Does anyone know how?

Good morning Martin! I tried to create it here, but no condition or validation worked. Can you exemplify me how you would do it?

Hi @Warly Silva welcome on the community. I don't think it is use case for Automation. You should use Condition or Validator on the workflow transition:

* condition = user can't see the target status if the condition fails
* validator = transition can be executed but it fails if the condition is false

Do you know how to set up validators and conditions?
