Scriptrunner condition not stopping transition

[Kev Fish]

I have a script runnter condition to prevent a transtion under certain conditions and despite the code returning false (which I've confirmed with logging) the transition is not blocked/still availiable.

Having looked at similar posts I can confirm that I am returning an InvalidInputException

The code used is the same I have in place on another project/workflow where is works fine

Any ideas ?

A condition doesn't return an InvalidInputException - they don't work with input at all.

A condition stops a transition from being offered to, or run by, a user.  They simply return "true" for "they can do this" and "false" for "they can not".  They determine what transitions appear (or allow to be triggered by drag and drop on a board)

So, I'm a bit confused on what you're asking about?
