nginx returns html instead of json response

[Kaushal Shriyan]

Hi Francis,

I tried the below to handle JSON responses from the PHP-FPM backend.

*Line no from 1 to 4(*nginxtest.conf*)*
map $sent_http_content_type $enableerror {
    default                    on;
    application/json          off;
}

*Line no from 46 to 51**(*nginxtest.conf*)*
location = /error-500.html {
             if ($enableerror = "on") {
             error_page 500 /error-500.html;
             root
/var/www/html/gsmaidp/web/servererrorpages/error-pages-500-503/html;
             }
      }

I have attached the nginxtest.conf file for your reference. It is not
working for me. Am I missing anything? Please guide me.

Best Regards,

Kaushal
