Create Assembly instance

Revit
1

Hello,

I manually created an assembly in Rhino using Rhino’s UI (“Modify” tab->Create Assembly).
And then I would like to create a new assembly instance with Python node, by using PlaceInstance method.
It works without issues, however, every time I run the Python node, the following dialog box appears at PlaceInstance method line:

Is this normal behavior of this method?
Is there a way to suppress this dialog box?

I would be grateful for any kind of help.

Attached are files. I am using Revit 2019.2, Dynamo 2.0.2.68, and IronPython2 engine.

# load libraries
import clr
clr.AddReference('RevitServices')

from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

clr.AddReference('RevitAPI')

from Autodesk.Revit.DB import *

doc = DocumentManager.Instance.CurrentDBDocument


# inputs
assName = 'assemblyProba2'
insertPt = XYZ(50,0,0)

if IN[0]:
	# a) get all assembly instances
	elColl = FilteredElementCollector(doc) \
	            .OfClass( clr.GetClrType(AssemblyInstance) )
	
	elColl.WhereElementIsNotElementType() 
	assembly_el_L = elColl.ToElements()
	
	
	# b) take the one with 'assName' 
	for el in assembly_el_L:
	    if el.Name == assName:
	        assemblyType_id = el.GetTypeId()
	        break
	

	# c) insert assembly instance
	with Transaction(doc) as t1:
	    t1.Start("insert assembly instance")
	    
	    el_assemblyInstanc = AssemblyInstance.PlaceInstance(doc, assemblyType_id, insertPt)
		
	    t1.Commit()
	
	OUT = el_assemblyInstanc
