Nginx 500 error page is not working with matches any unmatched URL -

in nginx conf. error 500 rule not working location conf. lines below.

location / {   try_files $uri $uri/ @rewrite; }  error_page 500 /error.html; location = /error.html {   root /path/to/nginx;   internal; }  location @rewrite{   rewrite ^ /index.php?q=$uri; } 

the error.html file in /path/to/nginx directory. when create 500 error in code, couldn't run nginx 500 rule. if remove location / { part, , change 500 404, works.
