Error getting value from 'WorksharingCentralGUID' on 'Autodesk.Revit.DB.Document'


I am super new to Dynamo and want to write my windows in a json file. but when I connect my directory to stringify.Json, I get this error :

Warning: Data.StringifyJSON operation failed.
Error getting value from ‘WorksharingCentralGUID’ on ‘Autodesk.Revit.DB.Document’.

What does this mean? How can I correct this?

Do you have the most current version of the package installed?
Also, what version of Revit and Dynamo?

Seems to be working for me:

Hi Sean,

I only get this error for windows. Room and electrical fixtures seem to have no problem.

I am using Revit 2020 with Dynamo Core Dynamo Revit

I believe you’re passing a Revit element instead of a string for the Level parameter. Try pulling the level’s name after you pull the element out.

Thanks Jacob.
It works with removing the level from the parameter list. But I don’t understand why I can get levels inside my room list but not window list.
