Why ‘All Elements of Category’ doesn’t work with Duct and Pipe Tags?
Warning: ElementQueries.OfCategory operation failed.
An internal error has occurred.
how can I resolve? I want to change the Tag Color via Dynamo.
It seems like a Dynamo error. Can you try with All Elements of Category+ from Clockwork?
Which Revit version are you in?
@Revit_Noob can you please check the dynamo and revit versions ? Or hotfix updates ?
As it is perfectly working in my system as shown in below snip

Tried it again just now am still getting same error.
How can I fix?
I believe this was addressed in a modern build (~4 month warning!) as noted by others above, but for now try to get the family types followed by all elements of family type.
You could also get elements dependent on pipes/ducts and filter by category.
