Nginx error : open failed 2 no such file or directory

Server NGINX
1

Hi,

I’ve written a small nginx module that serves files (with some extra
functionality). When I access the files through HTTP POST, I get below
error

[error] 2971#0: *184 open()
“/home/user/build/default/main/nginx/extern-nginx-prefix/nginx/html/1/3/49123876”
failed (2: No such file or directory), client: 127.0.0.1, server:
localhost, request: “POST /1/3/49123876 HTTP/1.1”, host:
“localhost:9000”

HTTP client uses URI as 1/3/49123876. And the call is routed to my
module correctly, however, the nginx log shows above error. I’m not
sure why is nginx trying to look into
/home/user/build/default/main/nginx/ …

The module functions correctly and serves the files that are requested,
however, why would I see above error then.

Here is my nginx config: Please note ‘my_pass’ directive for my module
that handles the request.

        worker_processes 1;
        master_process off;
        daemon off;
        error_log stderr notice;

        events {
            worker_connections 256;
        }

        http {
            default_type application/octet-stream;
            keepalive_timeout 60;

            client_body_in_single_buffer on;
            client_body_buffer_size 20m;
            client_max_body_size 20m;

            server {
                listen 9000;
                server_name localhost;
                location / {
                    my_pass /home/ubuntu/mugen_config.json;
                }
            }
       }
