TypeError: Cannot read property 'explorerPage' of undefined

I am upgrading jest from version 23 to 29. My project used to work fine before the upgrade, suddenly started observing this issue. I use Typescript as a language.

TestPageDefs Module looks like below:

import { lxExplorer } from "../pageObjects/explorer/lxExplorer.pom";
export class TestPageDefs {

  // Page object files
  public static explorerPage: lxExplorer = new lxExplorer();

}

This is consumed in another module/class.

import { TestPageDefs } from "../../helpers/TestPageDefs";

export class lxLinkAnalysis extends  BasePluginPage<lxLinkAnalysis> {

public  ebsLinkClassifyCountQuery: string = TestPageDefs.explorerPage.ebsTableQuery + " | link    'Log Source' | classify Count";
}

Getting below error.

TypeError: Cannot read property 'explorerPage' of undefined

I did tried other import like default or all imports (*). Nothing helped.
