external NPM modules are not loading after building cordova-electron@3.0.0

I am using cordova-electron@3.0.0 which I recently upgraded. I need to use some of the npm modules to work with the main process but after building the application, those modules are not taking but it workes when I do run the application.
what would be the possible issue

Start by reproducing the difference between running and building an application with cordova-electron@3.0.0, focusing on external npm modules used by the main process. Compare the module-loading behavior and build output in both cases; done means those modules load successfully after the application is built.
