When I try to run this script I keep getting this traceback error. I found a post that said this Genius Loci Tag node fixes that error, but I’ve had no success. What causes this error? It’s always the last node that is failing. I also tried the spatial element node with Orchid, and it just yielded nulls (and crashed a few times…).
The traceback is saying that the object has no Id. This is in Revit 2021, Dynamo 2.6
Tried flattening my input lists, and I still get errors, this time, “ToXyz”
Hey,
Could you show us the outputs from the nodes going into the create tag node?
Cheers,
Mark
Hi,
Add a Flatten node after All Elements of Category+ and after Room.Location nodes
I replicated your issues…
Then I threw in 1 room pruned out unplaced rooms which were giving nulls in the location and then it worked 
Then I plugged back in all the rooms, and it didn’t work.
Then I tried running with each room in a sub list and each set of rooms and locations in a matching sub list and running at level 2, also no luck.
I’ll let Alban take over from here 
Any ideas? I’m stuck for now…
Please show us all the previews under the inputs of the Create Tag node.
As Mark had pointed out, you have to filter out the unplaced rooms. (with a List.FilterByBoolMask for example)
You can’t tag them.
I did that a different way before, but decided to try a new node that will only collect placed rooms and it worked! Thanks everyone!
