CodePudding user response：

requires a callback function but got a [object Undefined]

Sounds like your import is not importing what you expect it to. Maybe you need to use module.exports?

CodePudding user response：

Syntax problem

I Have to write this

app.post("/register", register);

instead of this

app.post('/register', register);
