TOC - Layers in the App is not showing

Question

Good Day,

I’m trying to use the custom TOC widget in Enterprise

I have the widget setup properly and added to my app (through web AppBuilder):

In the app none of the layers show up:

I can confirm the layers are present in the map/app, as per the default Layer List widget:

Can someone help troubleshoot/fix?  Thanks,

Solution found: the group names were too long, there was a character limit exceedance that was causing the entire widget to break.  I don’t know what the exact character limit is that the app will work with, but the group name I found causing the issue was 57 characters long (with spaces).
