Session cookie not being passed from server to client

I have a client and server on Railway - a graphql server and a Remix app. On localhost my code works fine - I can login normally with a session that is passed from my backend and then set on my client. However, this session is not being passed to my frontend. I had the same issue on Heroku (I just recently migrated code from it to Railway) and I thought it might be specific to Heroku due to it being on some public list https://devcenter.heroku.com/articles/cookies-and-herokuapp-com but seeing as how it's doing the exact same thing on Railway, doesn't seem to be the issue (Unless railway is as well). Attached you'll find code of the relevant stuff. Any help here would be super appreciated.

Applications in the herokuapp.com domain are unable to set cookies for *.herokuapp.com.

Solution:
Should app.set('trust proxy', true) work?

both on railway and on heroku your app sits behind a proxy, look into how you would set cookies behind a proxy
