Fix App Errors - Build Errors, Google Maps Errors and CORS errors ( Mix of Ionic Vue & Vue Js Code)

I have developed an app using VueJs and Ionic Vue frameworks that uses Google Maps. The app is working as expected on the localhost, but it generates build errors when I try to build it for deployment. Google Maps is also not well set. I am looking for a developer with Vue Js and Ionic Vue expertise and experience to help in the following tasks:

1. Fix the APP to access Google Maps Key from the development environment.
2. Fix CORS errors
3. Fix build errors and Generate signed APK for Android and IoS app.

See screenshots for the errors the app generates. This is a very simple task for an experienced developer. Please dint bid if you have no idea of how to go about the tasks.
