NGinx

To serve the ApiPlatform index it's better to use nginx or to install this one: https://symfony.com/doc/master/setup/built_in_web_server.html

NGinx config

// start-php-fpm script
@ECHO OFF
ECHO Starting PHP FastCGI...
/pathToYourPhPWithOrWithoutXdebug/php-cgi -b 127.0.0.1:9123

// nginx conf

    ...
    server {
		listen 85;
		server_name localhost;
		root /pathh_to_the_project/sf-flex-encore-vuejs/public;

		location / {
			# try to serve file directly, fallback to index.php
			try_files $uri /index.php$is_args$args;
		}

		location ~ ^/index\.php(/|$) {
			fastcgi_pass   127.0.0.1:9123;
			fastcgi_split_path_info ^(.+\.php)(/.*)$;
			fastcgi_index  index.php;

			# When you are using symlinks to link the document root to the
