I try configure my Google Cloud Functions by using CDN. I try use this tutorial: https://cloud.google.com/cdn/docs/setting-up-cdn-with-serverless
With one function as Backend Endpoint looks all good, and if I open Load Balancing Frontend IP I see same result as I open direct function URL. And seems that this means this function now work over CDN if I use this IP.
But I have too many functions, because of this I try use URL mask for all functions in my Endpoint. URL mask looks like this:
https://us-central1-my-real-project.cloudfunctions.net/<function>
Problem that I cant understand how I can use Load Balancing Frontend IP for my Endpoint with Cloud Functions created with URL mask. When I open Load Balancing IP I get:
Error: Not Found
The requested URL / was not found on this server.
PS. Same if I try open http://<load-balancing-frontend-ip>/my-function-name
UPD:
Configurations in screenshots placed in google drive:

(sorry, not know how share other way configuration, and cant attach images direct in question because of low reputation)
As described in the documentation, the URL mask must be only /<function>. No URL before.
