Need help extending GetServerSideProps interface

[hugo-marques-m3]

Hello everyone :)

Background: I have a custom server where I use express and have a redis session.
I need to access a value inside of req.user but I'm getting a typescript error saying user doesn't exists

Property 'user' does not exist on type 'IncomingMessage'.

I've been trying to extend the interface to include the type definitions of the req.user object but with no success.
If anyone's done this or knows how to achieve this I would really appreciate it.

Thanks
