[Bug]: Cannot access x-forwarded-host in getServerSideProps

[brightonmike]

Summary

Locally, including when using netlify dev I can use x-forwarded-host header.

But once deployed, it's not populated. In fact, I can't find a way to access the hostname within getServerSideProps at all.

I'm looking to trigger a function from a page route, and just can't see how to achieve this.

Expected Result

x-forwarded-host returns site hostname

Actual Result

x-forwarded-host is not populated

Steps to reproduce

1. Attempt to access context?.req?.headers['x-forwarded-host'] within getServerSideProps
