The Cloud Firestore API is not available for Firestore in Datastore Mode database projects/<xxx>/databases/(default).

I have a google sign in popup inside my sign-in component or page(Reactjs). This google signInWithPopup functionality imported from firebase/auth is inside my firebase.utils.js file where I have called this signInWithPopup function with the auth produced from getAuth functionality on the initialized firebase app imported from firebase/auth and the GoogleAuthProvider functionality with the prompt as select_account imported from firebase/auth. Google sign in popup is working fine. I want to create user instances inside of Firestore. We don't have document references inside our database. I'm able to console log the DocumentReference object generated by Google using the doc functionality imported from firebase/firestore. I'm not able to console log the user snapshot i.e, using the getDoc functionality on the DocumentReference object generated by Google imported from firebase/firestore. It is throwing the error shown in the images.
