Has anyone ever done a ValidateLine client script on an Expense Report? I am running into an issue where even though the script is returning true, it's stuck on the line I'm attempting to add. I actually have the same script deployed to other records and it's working there correctly, too.

the normal debugging approach is to disable other workflows and scripts deployed to that record

Actually, I think I found the problem on this - had to set

ignoreFieldChange: true
