Action

Click on the tab named Tip.type to switch back to the Type Editor.

Double-click on the url attribute, and check the "Part of Database Key" check box, then click the OK button. The reason for using the url (and only the url) for the database key, is that each tip has a unique URL.

If we navigate back to the robot, we can see that the red underline has disappeared, and the Store in Database action is configured correctly.
