Always return "missing credentials"

This is my implementation with coffeescript and Express 4

passport.use new LocalStrategy
   usernameField:'emailAddress'
,(username,password,done) ->
   console.log('credentials passed to passport' + username + '' + password)

  User.findOne emailAddress:username,(err,user) ->
    if err then return done(err)
    if not user
      return done(null,false,message:'Incorrect data')
    bcrypt.compare password,user.password, (err,isMatch) ->
      if err then return done(err)
      if isMatch then return done(null,user)
      else return done(null,false,message:'Incorrect data')

#Authenticate user
app.post '/api/v1/auth/login',(req,res,next) ->
  passport.authenticate('local',(err,user,info) ->
    error = err or info
    if error then return res.status(400).json {user:null,state:'failure',error:error}
    req.logIn user,(err) ->
      if err then return res.status(400).json {user:null,state:'failure',error:err}
      res.status(200).json {user:req.user,state:'success'}
  ) req,res,next

I’m also using a linkedIn-strategy

I testing with an angular app and also with

 curl -v -d '{"emailAddress":"[e-mail]","password":"test"}' http://127.0.0.1:8070/api/v1/auth/login --trace-ascii /dev/stdout -H "Content-Type: application/json"

But I only get this

{"user":null,"state":"failure","error":{"message":"Missing credentials"}}

can you see the problem?

My problem was that I was using bodyParser to parse request body as json:

app.use(bodyParser.json());

If you have an html form and are posting username/password to the server, you need to ask bodyparser to parse urlencoded body:

app.use(bodyParser.urlencoded({ extended: false }));

i do not know if it would be helpful to somebody but : i solved the same problem by checking the password input name , it had a capital P !
