nginx warn: using uninitialized "subdomain" variable while sending response to client

See original GitHub issue

Nginx error log has many lines like these:

[warn] 32237#32237: *122 using uninitialized “subdomain” variable while sending response to client, client: 1.2.3.4, server: jitsi.example.com, request: “GET / HTTP/1.1”, subrequest: “/config.js”, host: “jitsi.example.com”

Seems like the $subdomain variable is called but not initialized in the vhost template.

Thanks for pointing me in the right direction. Maybe i’m wrong but shouldn’t the $subdomain be set to an empty string here?

location = /config.js {
    set $subdomain "";
    alias /etc/jitsi/meet/jitsi.example.com-config.js;
}

because, if a subdomain is really used, it will be catch by the block bellow:

location ~ ^/([^/?&:'"]+)/config.js$ {
    set $subdomain "$1.";
    set $subdir "$1/";
    alias /etc/jitsi/meet/jitsi.example.com-config.js;
}
