There are some issues in redux fundamentals here.

A store should be created once. Whenever, you select a topic , you will have to update the store but not re-create them. Move the createStore code accordingly.

Since you are using only one reducer, the following should be code to create a redux store. You were passing an object as a second argument which is a place for a redux middleware but not any other argument or parameter

# Definition for an interval.
# class Interval:
#     def __init__(self, s=0, e=0):
#         self.start = s
#         self.end = e

class Solution:
    def minMeetingRooms(self, intervals: List[Interval]) -> int:
        import heapq    
        heap = []

import heapq

class MaxInt(int):
  def __init__(self,val):
    self.val = val
  def __lt__(self,other): return self.val > other.val

class heap:
  def __init__(self, arr =[], num_type = int):
    self.arr = arr

//Note:  some may have selectedWidget, some may not , ignore it if it is not yours.
// while selecting a module, set topic and selectedWidget to null so that you don't retain the existing selection
// while selecting a lesson, set widget and selectedWidget to null

// This is just a sample code
  this.state={
// ...
selectedModule: course.modules[0],
selectedLesson: course.modules[0].lessons[0],
