how to make Nginx use home directory as root

I have set up a local server on my laptop for web development and to check the website I'm working on I should have my code base in */var/www/example.domain* which is not so convenient, I want Nginx to retrieve the files and parse PHP from my home directory, something like */home/projects/test-one/* but if I add this directory to root it'll throw me a **502 Bad Gateway** error here's my configuration: server { listen 80 default_server; listen [::]:80 default_server; server_name _; location / { root /home/amirreza/Projects/escribir/; index index.php index.html index.htm; } location ~* \.php$ { fastcgi_index index.php; fastcgi_pass 127.0.0.1:9000; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param SCRIPT_NAME $fastcgi_script_name; } } in */etc/nginx/sites-available/default*, I'm on Debian 11
