@erbinlim you will need to have access to an "Automation Node", not only a "Design Node". The automation node is a separate instance of Dataiku that is meant specifically for deploying projects. Do you have the access to an Automation node?
Check with your admin for the address. If you have (or they can give you) access you will see the information on your main project-list page when you logon. The screenshot below is the page I see when I log onto my automation node.
