TypeError in NestJs project when using jest.mock("common-package") in conjunction with ConfigModule

I am working on a project in NestJs and I am facing a problem. We have a common-package and I have implemented a custom implementation and module for it. The module looks something like this:

@Module({
  imports: [
    ConfigModule.forFeature(ConfigurationLoadedFromYamel),
    HttpModule.register({
      timeout: 5000,
      maxRedirects: 5,
    }),
  ],
  providers: [Providerq, Provider2...],
  exports: [Provider1, Provider2],
})
export class CustomeModule { }

Functionality-wise, everything is working fine. However, we have used jest.mock("common-package") in various test files across different services. The jest tests in the service test files where jest.mock("common-package") is used are failing with the following error:

● Test suite failed to run
TypeError: Cannot read properties of undefined (reading 'KEY')

     |                ^

Could you please help me understand why this issue is happening?
