Use MapLayersWidgetControl to report an error

[shenshengyi]

hi，When I use MapLayersWidgetControl, an error always appears, prompting ：Thanks.

@shenshengyi how are you including the MapLayersWidgetControl into your application? The MapLayerSettingsService.onCustomLayerNameRemoved looks to be a static property that is initialized by default so not quite sure why it'd be undefined.

Hi.
I added "@bentley/map-layers": "^2.10.0", or "@bentley/map-layers": "^2.12.0" to package.json, and when I use npm install, just run the program Will report this error.

This error disappeared when I used npm i @bentley/map-layers to install the dependencies.

first:
await MapLayersUI.initialize(false, IModelApp.i18n);

than:

I found that there is no such field in the generated *.d.ts file.

@shenshengyi you should check what version of the package actually got installed. The onCustomLayerNameRemoved property was introduced long after 2.12.0 - most likely you had installed a version from before that property was introduced.

Thank you very much, I understand, I did fail in version 2.10. Let me upgrade the version.
