I was recommended on my previous post by a community member regarding the use of firebase firestore database to download an app called make-it-so that uses firestore database, in order to learn how it works. I have tried a few times to make the app work but I keep on getting this error, any idea why? Any help is much appreciated!

Error message:

once done check if the google-services.json file exixt if it not there ask for it to the owner project and then it will work
