Im developing a website using Cloud9, trying to create a login
using passport connecting to a MySQL database but when testing in
postman i get the error shown in the print
The error occurs in this line of code: res.status(jsonMessages.users.signinSuccess.status).send(req.users);
I cant apply the method signinSuccess to the users because it is undefined
Any help would be appreciated
