Server not working or unable to sign up

[Lewsik]

I am unable to go past the sign up and log in screens when commenting out the lines as stated on the instructions. When not commenting out those lines, the server side of the app will not start.

Steps I followed:
-Started Postgres container as stated on instructions.
-Cloning repo.
-Going into server file.
-Doing npm install.
-Starting server with npm run dev.
-Going into client file.
-Doing npm install.
-Stared the app with npm start in a different terminal.
