I am trying to create a List Tile by following the steps given in the document "https://community.jivesoftware.com/docs/DOC-113609" while configuration window appears . It is giving error as "This view should be showing activity or information provided by an add-on, but it was unavailable. Your site administrator may be able to help."
Looks like your config URL is correct but the config data is not loading. I'd go over the clientconfig, but definitely check the custom config field you're defining: jiveclientconfiguration.json - Definition
