Definitely seems like cache issue with the record for express-session.
try sudo npm cache clean? After that try manually clearing the cache files?

@a_5mith yep

fuser -k 3000/tcp

seem to fix it so it will kill all to processes using that port

It may do work. But it is not very clean and can lead to serious problems to solve problems of this kind that way.
Just a little advice. No offence. 😉
