Selection Set ERROR: Invalid argument pSelSet in AddItems

[tanmayms3009]

Hi, 

I was trying to create selection set for some selected objects present in my AutoCAD drawing using Python, when the below mentioned error was thrown:

"self.__com_Invoke(memid, riid_null, lcid, invkind,
_ctypes.COMError: (-2147352567, 'Exception occurred.', ('Invalid argument pSelSet in AddItems', 'AutoCAD', 'C:\\Program Files\\Autodesk\\AutoCAD 2018\\HELP\\OLE_ERR.CHM', -2145320939, None))"

To control the type of items present in the array of objects I filtered out my model with only circles, but still, the error was there.

Here is my code :

"

from pyautocad import Autocad

acad = Autocad(create_if_not_exists=True)

ss = acad.doc.SelectionSets.Add("ss1")

arr_object = []

for i in acad.iter_objects_fast(object_name_or_list="AcDbCircle")

    arr_object.append(i)

ss.AddItems(arr_object)

"

Can anyone please guide me on how to deal with this error ?

Thanks in advance.

Thanks for your prompt response @devitg ,

I am sorry that I did not mention "Python". I want the solution in Python itself.

Kind regards.
