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

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

That error doesn't mean much without context. It's probably a syntax error or an improper import statement. Can you post your code?

I can certainly do that. Please see attached.

Thank you very much.

Are you having issues at runtime or in the Build Mode? The most questionable thing I am seeing is in the Setting.tsx. I don't think it is valid to assign and deconstruct in the same statement.

const { useMapWidgetIds = [], useDataSources = [] } = props

This line should probably just be this:

const { useMapWidgetIds, useDataSources } = props

I appreciate your response very much.
It is happening during runtime. I tried your suggestion and I still get the same error in runtime.
