[QUESTION] req.session.user undefined about session HOT 5 CLOSED

Update

I made a new project, on stackblitz.com, to store, increase, and reset a count number.
It shockingly works great there!!!

The only difference is, in this project, I'm checking if the req.session.count is undefined and I assign a default value.
Oh and Node versions. But I tried on my local project with versions 18.1.0 and 16.18.0 and same issue.

Update 2

Beliving that I could only store primitives in the session, instead of storing the whole User object, I stored it's id, to later find the user with the id from the users array.

The id from the session comes undefined!!!

Solved

The counter example worked because I made the requests in the browser, so the session could be stored in cookies.
The other examples, I made the requests via Rapid API Client extension in VSCode (and apparently it doesn't store cookies, new to me). Another test I made, was using another script, that used the node-fetch api, to make the login/register/user requests to the express server, and apparently, that doesn't store cookies as well.

So after I decided to make an user interface in the browser, to test this deeper and to be able to make the request pressing buttons, it worked right away! And then I checked the Application > Cookies and the session was there,
and the user is being returned.

I hope this experience is helpful to someone in the future (or to my forgetful future self wink).

Note: I normally test everything with an user interface in the browser, but this time I'm recording tutorials to teach a relative about NodeJS, TypeScript and soon Vue 3 and Nuxt 3, so that made me go back to the "root", vanilla everything :P

Update

I managed to get it working in VSCode > Rapid API Client extension.
I just had to pass the Cookie to the /auth/user GET request. Wondering why in the browser it happens automatically...
even though in Rapid API Client extension I have the options:

Anyway, looking great!

Last Update (I promise!)

The issue was with Rapid API Client VSCode extension.

I switched to Thunder Client extension, and I didn't have to set cookies manually! Phew!!! 😂🙄😔🤡
