errorhandler in flask and nginx server

I am using the following errorhandler in my flask app

@app.errorhandler(413)
def error413(e):
    return render_template('error413.html'), 413

which shows an error page if error 413 happens (filesize too large). This works fine on my localhost, but on the server I get the nginx 413 error page instead.

413 Request Entity Too Large
nginx/1.4.6 (Ubuntu)

Is there anything which is different between nginx server and localhost regarding error handling? I use gunicorn together with nginx... thanks carl

By default, nginx catch HTTP error codes. It is a good thing, for security purposes.

It is possible to disable this behaviour, you can set uwsgi_intercept_errors off.

http://nginx.org/en/docs/http/ngx_http_uwsgi_module.html#uwsgi_intercept_errors

You can use custom static error pages, served by nginx. Example:

error_page 413 /custom_413.html;

location = /custom_413.html {
    root /usr/share/nginx/html;
    internal;
}

Just set it to all error codes you want to handle.
