laravel lumen project as subdirectory with nginx

[tdchien]

Hi everyone,
I'm trying configure a project using lumen laravel with nginx on laragon.
But I'm having a problem when make it run as subdirectory.
Example domain run at http://project.local/api/ and project located at D:\projects\api
Does someone has experiment with this case, please give me some suggestion.
There is my current config

server {
	listen 8172;
	server_name project.local;
	charset utf-8;

	root "D:/project/home";
	index index.html index.htm index.php;

	location / {
		try_files $uri $uri/ /index.php?$query_string;
	}

	location ^~ /api {
		alias "D:/project/api";
		try_files $uri $uri/ @siteApi;
		location ~ \.php$ {
			include snippets/fastcgi-php.conf;
			include fastcgi_params;
			fastcgi_pass php_upstream;
			fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
		}
	}
	location @siteApi {
		rewrite ^/api/(.*)$ /api/index.php/$1 last;
	}
	location ~ \.php$ {
		include snippets/fastcgi-php.conf;
		include fastcgi_params;
		fastcgi_pass php_upstream;
		fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
	}
	location = /favicon.ico { access_log off; log_not_found off; }
	location = /robots.txt  { access_log off; log_not_found off; }
	location ~ /\.ht {
		deny all;
	}

	gzip on;
	gzip_vary on;
	gzip_disable "msie6";
	gzip_comp_level 9;
	gzip_min_length 1100;
	gzip_buffers 16 8k;
	gzip_proxied any;
	gzip_types
		text/plain
		text/css
		text/js
		text/xml
		text/javascript
		application/javascript
		application/x-javascript
		application/json
		application/xml
		application/xml+rss;
}

Thanks
