我已经使用弹出 UX 模式为 Firebase 上托管的 React 网站实现了“使用 Google 登录”。我可以登录，但是，每次登录 localhost:3000 或网站的部署版本时，都会收到以下错误：

    "database": {
        "rules": "database.rules.json"
    },
    "functions": {
        "predeploy": ["npm --prefix \"$RESOURCE_DIR\" run lint"],
        "source": "functions"
    },
    "hosting": [
        {
            "target": "sandbox",
            "public": "build",
            "ignore": ["firebase.json", "**/.*", "**/node_modules/**"],
            "rewrites": [
                {
                    "source": "**",
                    "destination": "/index.html",
                    "headers": [
                        {

                            "value": "same-origin-allow-popups"
                        }
                    ]
                }
            ],
            "headers": [
                {
                    "source": "**",
                    "headers": [
