How to set errorfile in haproxy, default_backend?

Hello everyone
Plz tell me how to set errorfile in default_backend?
I looked at the docks (although I ran through my eyes, I didn’t really delve into it), I read Google, I did this:

frontend:
...
default_backend example-bck

backend example-bck
   mode http
  errorfile 403 /etc/haproxy/errors/403.http

but on request is given

<html><body><h1>503 Service Unavailable</h1>
No server is available to handle this request.
</body></html>
