LiyerList widget - bug introduced at version 4.18 - Angular

Question

I recently upgraded my application from version 4.17 to 4.18 and came to realize that the LayerList widget still works but throws now the following error: "view: no layerview has been found for the layer"

I tried to reproduce this error using the sample from ESRI https://developers.arcgis.com/javascript/latest/sample-code/widgets-layerlist/  and replace the map layers with my own layers: there was no error

Then I recreated a sample app with angular and I was able to reproduce this error again. This error seems to happen in an Angular project using esri-loader and @types/arcgis-js-api

I ended up reverting back my application to version 4.17

Thanks Richard. Those errors might be related to another issue we are working on. I'll make a note to take another look at this once we have a new /next build to test with a potential fix.

Hi Andy, thank you for the quick response. Above is the stackblitz sample that reproduces the error: Angular 11, "@types/arcgis-js-api": "^4.18.0"  and "esri-loader": "^3.0.0"
