如何在Swift中解决oAuth的Firebase错误。 FIRAuthErrorDomain代码= 17999

Question

我的create auth用户方法不再起作用，并且遇到了以前从未见过的错误。我检查了GoogleService-Info.plist，所有值都与我的Firebase仪表板匹配。甚至重新下载它以确保。我切换了登录方法，还从Google Cloud Platform启用了Identity Toolkit API。

找到了一些关于Stack Overflow的好的答案，但与“ status =” PERMISION_DENIED”内部错误无关。任何反馈将是巨大的！ -这是完整的错误消息

Error creating Auth createUserWith(email:password:completionUser:completion:)

                domain = global;
                message = "Requests to this API identitytoolkit method google.firebase.auth.v1.IdentityIdaasAuthenticationService.SignUp are blocked.";
                reason = forbidden;
            }
        );
        message = "Requests to this API identitytoolkit method google.firebase.auth.v1.IdentityIdaasAuthenticationService.SignUp are blocked.";
        status = "PERMISSION_DENIED";
    }}}} An internal error has occurred, print and inspect the error details for more information.
