Node.js - How to remove item from express session

I tried to remove an item I recently added to the session from the session. But I'm getting an error:

console.log('req.session:');
console.log(req.session);

req.session.checkout = 'Test';

var getSession = req.session;
console.log('getSession:');
console.log(getSession);

var { checkout, ...ret } = getSession;

console.log('ret:');
console.log(ret);

req.session = ret;

console.log('req.session:');
console.log(req.session);

console.log('req.session.checkout:');
console.log(req.session.checkout);

console:

req.session:
Session {
  cookie:
   { path: '/',
     _expires: 2020-07-16T12:04:03.332Z,
     originalMaxAge: 900000,
     httpOnly: true } }
getSession:
Session {
  cookie:
   { path: '/',
     _expires: 2020-07-16T12:04:03.332Z,
     originalMaxAge: 900000,
     httpOnly: true },
  checkout: 'Test' }
ret:
{ cookie:
   { path: '/',
     _expires: 2020-07-16T12:04:03.332Z,
     originalMaxAge: 900000,
     httpOnly: true } }
req.session:
{ cookie:
   { path: '/',
     _expires: 2020-07-16T12:04:03.332Z,
     originalMaxAge: 900000,
     httpOnly: true } }
req.session.checkout:
undefined
TypeError: req.session.touch is not a function

How do I properly remove it, so I get as result the original state back without the error?

req.session:
Session {
  cookie:
   { path: '/',
     _expires: 2020-07-16T12:04:03.332Z,
     originalMaxAge: 900000,
     httpOnly: true } }

Late answer, but maybe useful for those who got stuck.

You can store sessionID = req.sessionID when you create the session. Then you can delete it from the session store.

 req.sessionStore.all((error, sessions) => {
   req.sessionStore.destroy(sessionID, (error) => {});
 })
