Do you have the correct Packages for your Revit + Dynamo version?
That is the only thing i can think of what is left.

PS
I tested it on Revit 2025.

Thank you very much for all your efforts

CLOCK WORK 2.12.3

bimorphNodes 3.03

dynamoironpython 2.4.0

revit 2024 I have also Revit 2025 can you share with me your dynamo package versions

25

Test it for Revit 2024 too and it worked there too.

Clockwork for Dyanmo 3.x - 3.0.3.
DynamoIronPython2.7 - 3.2.1
DynamoIronPython3 - 1.5.1
BimorphNodes - 5.1.3.

Note
I only tested for your original problem returning nulls for this node :backhand_index_pointing_down:

Thank you very much for all your efforts.

I will try to solve this issue it seems there is something wrong in my packages.

FamilyInstance.ByCurve may require IronPython as @bvs1982 has implied. Make sure you have the correct version of 2.7 installed. You can also “remove” the contents of the custom node and run them directly in your graph (probably just a python node) to see what warnings you get there.

Thank you very much for all your efforts.

as @bvs1982 has implied. I just use the correct package version and its work correctly now.
