Express Route Post Promise

So i have the following:

    signToken(payload) {

      return new Promise(function(resolve, reject) {

        if( ! payload ) {

          return reject('Payload not specified.');

        }

        jwt.sign(payload, secret, function(err, token) {

          if( err ) {

            return reject('Token not signed ' + err);

          }

          return resolve(token);

        });

      });

    }


    app.post('/', function(req, res) {

      clientToken.signToken(req.body.text).then(function(token) {

        res.cookie('cl_a', response, { domain: 'localhost', maxAge: 9000000, httpOnly: true});

        res.json({ message: 'Successfully Authenticated' });

        res.status(200).end();

        console.log('1');

      }).catch(function(err) {

        res.json({ message: 'Something Went Wrong' });

        res.status(403).end();

      });

    });

When posting on "/" with the payload the promise gets resolved but instead of executing ".then" the ".catch" part is running.

Can somebody help with a better example :D ?
