IS Renderer causing error in console

[simongis]

I have published a Mosaic Dataset to an Image Service with ArcGIS GIS Server 10.5. This has a couple of symbology raster templates embedded. (Paste of REST endpoint, and also RasterFunctionInfos).

These symbology renderers work as expected when added to ArcGIS Online

With the one image service added to a Web Map, when I add the IS Renderer widget to Web App Builder Developer Edition (2.4), I get the following error in my console when launching the widget:

init.js:113 TypeError: Cannot read property 'length' of undefined
    at Object.rendererRR (Widget.js?wab_dv=2.4:208)

Can someone help me troubleshoot what the issue might be?

Hi Simon, This is strange. It should work. Can you send me the link to the service so that i can test it out?
