What is the use of Elements in connected network? It is returning a null which is why you are getting an error. Connect the Select Model Elements directly to Element.Curves.

I done without “elements in connected network” node. but i didnt get the fitting in the cabletray

Does that node make fittings? I thought it only made the cable try and you have to add fittings separately.

Exactly, what @kennyb6 says: it will only create cable trays.
