Import bonita-task-list-page.zip in UI Editor fails

I tried importing bonita-task-list-page.zip just to change some of the UI design, but whenever I import it into UI designer, it gives the following message:

Incorrect zip structure. The artifact has not been imported.

Check that the zip archive contains one of following files ["page.json","fragment.json","widget.json"].
 
I tried opening the zip and yes, those files are missing. Is there any download link for the file that is complete and has correct structure? TIA

The Task list page is not designed with the UI Designer.

You can fork and update the user task list here
