When using a dynamic element such as a Card Deck, you may find that your build fails. Elements from the “Dynamic Views” section need to have a data source from an API request bound to them. Binding to a data source should resolve the issue, but we have an additional To Do checker planned for a future release that will help users avoid the problem. We’ll report back here as soon as the fix is available.
