Bug report

-->

• I confirm this is a bug with Supabase, not with my own application.
• I confirm I have searched the Docs, GitHub Discussions, and Discord.

Describe the bug

I'm starting to use read replicas to ensure my users get the fastest response possible all over the world.
I'm using Drizzle, so I cannot use the auto geo API from SDK.

I wanted to do it myself based on x-sb-edge-region as the doc in https://supabase.com/docs/guides/functions/regional-invocation say this value is available, btu it seems set after the function responds.

To Reproduce

Try to read the header in the edge function; you should have the region or an indication of where it's run from.

Expected behavior

x-sb-edge-region available

[laktek]

We expose the region to the function via SB_REGION environment variable on the hosted environment. More details here: https://supabase.com/docs/guides/functions/secrets

Would that be sufficient for your need?

Totally ! Thanks so much this should be in the doc of region invocation or read replicate.
It would be nice to have that automated as well in the env var or via a proxy
