'qSlicerScriptedLoadableModule' object is not subscriptable

Development

Hi all,

The following error was printed in the python interactor upon start-up after I added a custom module path to Slicer.

Traceback (most recent call last):
  File "~/CreateMesh/CreateMesh.py", line 43, in __init__
    self.smoothN = meshparams["smoothNumberOfIterations"]
TypeError: 'qSlicerScriptedLoadableModule' object is not subscriptable
TypeError: module() argument 'name' must be str, not qSlicerScriptedLoadableModule

Does anyone know what is the reason for this error? Below is a snippet of the custom module. Many thanks!
