I have followed all the steps as mentioned here.
Still I have problem in running the tutorial.
When I am checking it on console the following error is coming.
Please help me how could I correct it and where I have made the mistake.

Thanks @disha1202 .

The card popup doesn't appear. It should be there after the first popup.

Whenever I am trying to run this activity network error is occuring.Its happening with only this.Could you suggest any possible fix?

I guess it's when you try to click on an item? When you do that, the activity try to create a network share.
Because you're executing Sugarizer locally (file:///), it's normal that you've got an error message if you're not connected to a server.

Close due to lack of activity. @abhishek-sultaniya feel free to reopen it if need.
