Revit 2024 IsInput not recognized?

IsInput isn’t working from a script in dynamo player. I have the script hosted on ACC, and Dynamo Player is pointed at the \ACCDocs share. I’ve verified and cycled the checkbox on the Yes/No Boolean

However, when opened in Player, the option (post execution) isn’t available.

What am I missing here? Other scripts seems no issue. It seems related to being copied up to ACC, as when the script is not pathed to the Docs share on C: but local path on C: it works just fine with the IsInput option.

Try adding a nodes with an output (watch node renamed with a boolean input is fine) to see if that pushes the input. Might also be that you’re saving in a different location so double check that.


I tried all of the above, I created a new Boolean IsInput even, since I was unsure where to tie the IsOutput, I tried every possibly combination, including a second boolean just off to the side set to input/output as well, saved to a new folder location on ACC and remapped the dynamo player to the new location. This script does a lot of heavy listing organizing linear feet of pipe/fittings and compiles them on to reels available for sale, so it’s a real chore to rebuild from scratch. It is a migrated Revit 2022 script.


Somedays you learn something new… I need to click on the picture for Script options, it’s been working the whole time. I just started using 2024 with Dynamo, so the new interface is a bit unfamiliar.
