Most of the assets are not deleting while trying to delete, it shows Network Error? Any help/leads?

[Risikanta Pradhan]

I have more than 2000 assets in my object schema, which includes many duplicate assets.
I am trying removing them manually one by one as well as through the bulk Delete method using the Delete button, but when I try to do so, it shows, 

"We couldn’t delete your objects.

Please check your network and try again"

Hi Rishikanta,
Something similar happened to us in our Assets and is impossible correct it.
Check if appears the attributes: Key, Created and Update
If these not exist the object is corrupt, check if you can export the content in a csv archive and recreate this object.

Note: if you have any type objet attribute, you must recreate all links from or to this attribute.
