vercel dev express session not working?

[Youdaman]

I've noticed that session (using express-session) vars, e.g. req.session.foo = 'bar', do not retain their value when using vercel dev -- works fine in production though. Also works fine locally if running the script directly via node.

Sorry @PieroJacinto I'm no longer working on the project that was using this.
