我正在Laravel中开发一个应用程序，当我按下折叠按钮时，控制台显示“TypeError：无法将配置转换为字符串3 app.js：3449：52
我的package.json是：

{
    "private": true,
    "scripts": {
        "dev": "npm run development",
        "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
        "watch": "npm run development -- --watch",
        "watch-poll": "npm run watch -- --watch-poll",
        "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
        "prod": "npm run production",
        "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
    },
    "devDependencies": {
        "axios": "^0.19",
        "bootstrap": "^4.4.1",
        "cross-env": "^7.0",
        "jquery": "^3.2",
        "laravel-mix": "^5.0.1",
        "lodash": "^4.17.13",
        "popper.js": "^1.12",
        "resolve-url-loader": "^2.3.1",
        "sass": "^1.20.1",

        "vue": "^2.5.17",
        "vue-template-compiler": "^2.6.10"
    }
}

我崩溃的密码是

<nav class="navbar bg-white shadow-sm navbar-light">
    <div class="container">
        <a class="navbar-brand" href="{‌{ route('home') }}">
            {‌{ config('app.name') }}
