ASE-Tutorials | Examples of using the Atomic Simulation Environment

Hello I am following this tutorial in order to do push notifications to multiple devices at once in Expo React Native using Firebase's cloud functions. The push tokens are stored in my RealTime-Database, but when I attempt to integrate this step after running firebase login and firebase init, I updated my index.js file to contain this code. After saving this file, I attempt to do firebase deploy and I get 70 errors. I tried to deploy it from my app directory, and didnt work, and I tried to do it from my functions directory and that didn't work. I deleted my node_modules and package-lock, and I tried to rerun expo again and clearing my npm cache. Nothing worked. I already had my firebase app initialized somewhere else, could that be the reason why? But my App itself still works, so I am not getting an error saying that the Firebase app is being initialized twice. I really dont know what else do to. Is the ESLint causing all of these errors? Should I run firebase init again without adding ESLint? Please let me know. My errors are below.
