Hello! I am trying to use the “Trigger a custom event when data changes” in a workflow. Essentially, information is sent from one user to another and when the receiving user clicks a button, a data field is updated. When this data field is updated, I would like to show a page on the initial sending user’s screen. I made a Custom Event defining all necessary parameters but no matter what I do, I keep getting this error message. If someone can just tell me what even the ‘argument’ is in this case and how to keep it to exactly one - that would be great!
