Hello to all! I ask for help, I recently switched to the new version of Revit 2020.1 and many of my plugins stopped working. I started looking for a problem. And it turned out that before, if I turned to Element if (e.get_Parameter (GUID)! = Null) { /// } If there is no parameter with such a guid, the method returned null to me, and now it returns 0. From the API, did something break?
