Describe the bug
Creating asset with owner's email is not getting reflected in the owner's field when we do a get request on the asset. (that is Asset fetching is returning empty owner's field) and

Creating asset with owner's uuid is giving an internal server error.

To Reproduce
Steps to reproduce the behavior:

1. Create an asset with body containing owner's information with these two cases
   case 1: with owner email only
   case 2: with owner's uuid ( will give an internal server error immediately )
2. GET / {HOST}//v1beta1/assets (for case 1)
3. See the owner's field for the asset

Expected behavior
Should contain owner details as defined during asset creation
