Hello,

Thank you for all the work on the Revit JSON exporter add-in.

For some reason the exporter fails when trying to filter the parameters of the objects to be exported. Please see below for a sequence of photos showing the general flow of the failure.

I am very inexperienced Visual Studio user. If more debugging information is required to show what's happening please make a specific request and I'll see if I can produce it.

Please note, this may be the same issue reported earlier for Revit 2019 as issue #17.

Best wishes,
Jake Staub
