serving pdfjs PDFs over nginx - nginx

Question

I am looking to serve pdf.js using nginx, but Iam having trouble with the example so far. So, I do the following:
git clone git://github.com/mozilla/pdf.js.git /some/location/pdfjs
cd /some/location/pdfjs
.. Now, I set up my nginx config file like so:
server {
listen 8181 default_server;
listen [::]:8181 default_server ipv6only=on;
# Make site accessible from http://localhost/
server_name localhost;
root /some/location/pdfjs/web;
index viewer.html;
access_log /some/location/access.log;
error_log /some/location/error.log;
location / {
}
}
When I run nginx now, I the PDF does not show up. I do see the pdf.js outer canvas though - just not serving the PDF file.
When I look at the error messages, I see:

Not sure if this has got to do with serving the actually PDF - would appreciate any suggestions to solve this.
