Qt-scripted-modules are not recognising using python interacter in slicer

Development
1

I have two python files.
1)plan.py
2)manager.py

plan.py - is like below.

import manager
def plan(baseDir=None):
m = manager.managerLogic(baseDir)
m.load(‘plan’)
plan()

Whenever I tried like below commands Its working using python interacter in slicer.

import plan
plan.plan()

But when i try like below. Its not working.

import plan

I have added above file inside scripting file also. (compile_Slicer_python_scripts.py). building is also fine.

ctk_compile_file(‘D:/W2/S-r/S-bld/Slicer-build/lib/Slicer-4.13/qt-scripted-modules/plan.py’, force=1)

May I know what is the issue here?

Why python module is not initiating by default?

I got some error message after launching the application. The log looks like below.
