Firebase geo-headers lost when hit from hosted web-app domain

[Nithin G]

Hi,
I've a web-app hosted in firebase, alongwith a firebase-functions. Basically I hit the function from the hosted-web-app to fetch host's ip-related geo information that is available in the request-headers in firebase-functions ("x-appengine-city", "x-appengine-country" & "x-appengine-citylatlong"). It is working absolutely fine.

Yesterday, I tried serving firebase functions from the same domain as the hosted web-app (not my custom-domain, the default domain that firebase hosting provides) by adding a re-write in firebase.json. When I hit that rewritten url from firebase, I get invalid values for "x-appengine-city" details (I get "??"). Even the "x-appengine-citylatlong" are "0.0000,0.0000" now.

Eventually I plan to add a custom-domain to my host, and access my firebase function through that domain, but I cannot do that if get the above values.

Is there any way where I can add a rewrite for the firebase functions and still have access to the geo information?

Thanks,
Nithin

Because Firebase Hosting routes all of your requests through a CDN, the original geographic information ends up getting lost along the way to the Cloud Function so that data is not currently available. I'd encourage you to file a feature request / bug report at https://firebase.google.com/support so we can track it internally.

Firestore’s internal GeoPoint query is not yet supported. I actually needed an implementation of something like this, so I chose the library geofirestore, this has the capability you are looking for.

I think the question is misunderstood (or maybe I did not understand your answer), but I am not using firestore (or any other data-store for that matter). Just the request headers from firebase functions.

Thanks. Have filed a bug-report. I guess this could be considered a bug.
