我将Firebase Auth用于网站，并选择了密码验证和Google登录。当我运行它时，我得到以下信息：
{"error":{"code":403,"message":"Requests to this API identitytoolkit method google.cloud.identitytoolkit.v1.AuthenticationService.SignUp are blocked.","errors":[{"message":"Requests to this API identitytoolkit method google.cloud.identitytoolkit.v1.AuthenticationService.SignUp are blocked.","domain":"global","reason":"forbidden"}],"status":"PERMISSION_DENIED"}}
我已经从Firebase控制台启用了密码和Google登录，并且还在Google Cloud Platform控制台中启用了Identity Toolkit API，但是仍然出现此错误。
