ReferenceError: actor is not defined

Hi All,
I am try to use codecept for our automating UI test case.we are using BDD structure
Below is my requirement.
1.Frame work code should be separate
2.Test code should access framework code for writing and executing the test case

Below thing i did.
1.separate framework code and test code
2.Created 2 folder
Framework code
Project code
In frame work code i have below file.
1.Node modules
2.Package.json
3.Index.json(Its the entry point in package.json)
4.Utility folder(Framework code)

In Test code:
1.test case
Feature file and steps file
2.Codecept config
3.Codecept helper(Puppeteer)

If we are trying to access utility file below error is displaying
ReferenceError: actor is not defined

Utility Code:
module.exports = (function() {

I = actor();

return actor({

/**

  • Input of this API is breadcrum navigation sequnce .

  • if you want to reach grandhchild then input(parent,child,grandchild )
