I have installed the LocalLayer widget which seems perfect for me to add some locally hosted dynamic maps within an app. I can configure the map to point at a local service successfully however when I try and use the button I get an error. I'm not sure if I have missed something in the configuration - it's the first time I've tried using web appbuilder with a custom widget?
TypeError: Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'.

Any help would be greatly appreciated.
