Error showing up when running npm run deploy:rules

Your application has authenticated using end user credentials from the Google Cloud SDK or Google Cloud Shell which are not supported by the firebaserules.googleapis.com. We recommend configuring the billing/quota_project setting in gcloud or using a service account through the auth/impersonate_service_account setting. For more information about service accounts and how to use them in your application, see https://cloud.google.com/docs/authentication/. If you are getting this error with curl or similar tools, you may need to specify 'X-Goog-User-Project' HTTP header for quota and billing purposes. For more information regarding 'X-Goog-User-Project' header, please check https://cloud.google.com/apis/docs/system-parameters.

This error message is caused by using User Credentials when you setup the Cloud SDK. Typically this is done using the command gcloud auth login. Create a service account and set up the Cloud SDK to use the service account and run the following command.

gcloud auth activate-service-account test@development-123456.iam.gserviceaccount.com --key-file=/fullpath/service-account.json
