NodeJS POST Form always return 404 - node.js

Question

I've been running through a problem and I can not find out what it is. I am using Express for this.
I have an "addUser" form which has the following Pug form :
form(action='/adduser', method='POST')
and I have try POST method in the app.js that doesn't work :
app.post("/adduser", function (req, res, info, next){
console.log('This does not appear');
});
What I don't understand is why the following login POST method which is just right above the adduser works perfectly :
app.post("/login", passport.authenticate('local', {
// login things
});
NB : At the beginning, the /adduser was in a router and was also returning 404, that's why I tried to move it in app.js .
Feel free to ask any informations that you need.
Anthony.

Answer 1

In your /adduser route you have 4 parameters in the callback function: (req, res, info, next). Remove info and Express will find your route.
With four parameters Express interprets your handler function as an error handler, see more information here: https://expressjs.com/en/guide/error-handling.html. Because of that you get a 404, as the request is passed through the middleware chain into the 404 handler.
