I just realized I should have raised this issue in https://github.com/thepassle/astro-firebase but I guess I can keep this here anyway. Let me know if I should open it on that other repo, @thepassle .

I've also added an example here: https://github.com/dperolio/immerse-testing

It is using the example SSR Astro demo (https://github.com/withastro/astro/tree/latest/examples/ssr) with astro-firebase added. You can see this issue when you try to deploy to Firebase and then run firebase functions:log
