I am initialising it like this.

var Botkit = require('botkit'),
  firebaseStorage = require('botkit-storage-firebase')({firebase_uri: 'https://xxx.firebaseio.com/'}),
      controller = Botkit.slackbot({
          debug: true,
          storage: firebaseStorage
      });

// then you can use the Botkit storage api, make sure you have an id property
var beans = {id: 'cool', beans: ['pinto', 'garbanzo']};
controller.storage.teams.save(beans);
beans = controller.storage.teams.get('cool');
console.log(beans);

However I can see the database entry posted on firebase console succesfully. problem occurs only on
beans = controller.storage.teams.get('cool');

Any idea how to get around this?

Looks like repo is outdated and uses firbase v2 api instead of new v3.fixed it by using this fork instead.

You can use firebase-admin with botkit-storage
