数据 migrate 成功，但访问 url 报错

报错信息如下：

ErrorException (E_ERROR)
Invalid argument supplied for foreach() (View: /var/www/html/morechina-shop/resources/views/user_addresses/index.blade.php)
Previous exceptions

routes/web.php:

Route::get('/', 'PagesController@root')->name('root')->middleware('verified');

Auth::routes(['verify' => true]);

// auth 中间件代表需要登录，verified中间件代表需要经过邮箱验证
Route::group(['middleware' => ['auth', 'verified']], function() {
    Route::get('user_addresses', 'UserAddressesController@index')->name('user_addresses.index');
});
