node.js Express with HTTP-AUTH

I have problem with creating node.js application based on express with http-auth module.

It's a posslible create Middleware for this http-auth library i have this code

    //Configure Middlewares
logger.configure(function() {

  //All output has content type json
  logger.use(function(req, res, next) {
    res.contentType('application/json');
    next();
  });

  //Create digest auth middleware
  logger.use(function(req, res, next){
    digest.apply();
    next();
  });
});

after appling this when i want connect to site i will get

TypeError: Cannot read property 'headers' of undefined

Is there any solution for this problem or use another method, i need have digest auth for whole application.

Thank you
