EB Custom Widget not able to connect to the layer from the map or directly to a layer

AbiDhakal

Dear GIS friends,

I'm working on a custom widget, but I am not able to connect the widget to the map layers. When I add the widget to a map I get this error: 

Minified React error #130; visit https://reactjs.org/docs/error-decoder.html?invariant=130&args[]=undefined&args[]= for the full message or use the non-minified dev environment for full errors and additional helpful warnings

Please help I'm naive.

Please see attached files if it helps.

I have done a lot of npm start on the server and client.

Thank you,
Abi
