Question

Created a lumen project in the api folder
In the api folder created a .htaccess file with the content:
RewriteEngine On
RewriteRule ^(.*)$ public/$1 [L]
In api/bootstrap/app.php I connected the Bitrix core
require($_SERVER["DOCUMENT_ROOT" ] . "/bitrix/modules/main/include/prolog_before.php");
Vendors are connected in local/php_interface/init.php I
go to the site using url /api/
An error appears
