Error: Argument at index 1 of UMD factory call is not a require call with a single string argument. When running npm install

First running

npm install leaflet
npm install @asymmetrik/ngx-leaflet

and then

npm i

gives me the following error..

Error: Argument at index 1 of UMD factory call is not a `require` call with a single string argument:
factory(require('@angular/core'),exports, require('@angular/core'), require('leaflet'))

If I then remove @asymmetrik/ngx-leaflet, installation works just fine..

I just published a new version of the library that's compatible with Angular 13. As part of the new version, I migrated to use the ng-packagr build pipeline for libraries. So, check it out and see if it resolves your issue. If not, provide more details (versions, build system, etc.) and maybe someone can help out.
