What are some constructs you can use to help solve the issue where the JSON data source does not have values for all elements and therefore the data does not line up correctly in the Klip? Select ALL that apply.

Use LOOKUP function to lookup from complete list of ids to list of ids that have a picture
Use the following-sibling or preceding-sibling constructs in the xpath
Use the custom kf:fill_elements function
Use the MAP function to iterate through each item and SELECT only the items that do have values for all elements
