Node.js Code Fix Required

Hello, I’m a beginner in programming.

I wrote some code and after running npm start I got this error:

"Error: Cannot find module 'express-session'"

plus 2 other errors.

I already reinstalled Node.js also module express and I’m using Node 18 on Windows 10 — could that be the problem?

Please, can somebody help me?
