I come across this error when running terraform apply. Google identity platform is enabled in my project.
Error: Error creating Tenant: googleapi: Error 403: Your application has authenticated using end user credentials from the Google Cloud SDK or Google Cloud Shell which are not supported by the identitytoolkit.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 Authentication overview | Google Cloud.
