Hi Shide,

We have recently migrated all Kendo UI for Angular packages and their latest versions are now shipped as Ivy libraries compatible with Angular 12 and 13. More details about the effort could be found here: https://github.com/telerik/kendo-angular/issues/3502

Having this in mind, please be aware that following the Getting Started guide will prompt the latest version of the Layout package to be installed, and if the existing project has an Angular version lower than 12 the package would not work as expected.

If upgrading the Angular version is not an option, we still offer support for Angular v8 - v11. Existing package versions are tagged with "ng8" through "ng11" on npm. These tags can substitute regular version numbers in both command-line npm usage and package.json, for example:

ng add @progress/kendo-angular-grid@ng11

If the project is updated to Angular v12.x or v13.x, then the Upload package would need to be respectively updated to its latest version, too. This should remove the 'override' error from the console:

In order to ensure that the packages are updated correctly and to avoid any cache-related problems:

1. Try deleting the node_modules folder and package-lock.json file.
2. Update the packages following the steps from the article.

I hope this helps.

Regards,
Martin
