javascript – Why is the state undefined when I run my unit test with a mocked state?

I’ve created a mock state in my unit test, however, when I run the test, I get a message that says: TypeError: Cannot read property 'flags' of undefined.

I found a similar post on StackOverflow and I followed the solution there: https://stackoverflow.com/questions/56399446/mocking-store-getstate, however, I still keep getting the undefined state error 🙁

Help is appreciated!

My function:

import {store} from "@store/Store";

const {getState} = store;

export const myFunc = () => {
  const state = getState();
  const flag = state.flags.booleanFlag;
  return flag ? "valid message" : "invalid message";
}

My unit test:

import {store} from "@store/Store";

jest.mock("../../app/store/Store");

const mockState = {
  flags: {
    booleanFlag: true,
  }
}; 

store.getState = () => mockState;


describe('Utils', () => { 
  describe('myFunc', () => {    
    it('should return the correct message when the flag is true', () => {
      const expected = "valid message";
      expect(myFunc()).toEqual(expected);
    });
  });
});

Note: The actual state of my application is as follows:

{
  flags: {
    booleanFlag: false,
  }
}
