[Bug]: Override custom query without thumbnail for product will break the app

Expected Behavior

Expect: the app should not break when I define a valid custom query (without thumbnail field)

Actual Behavior

It crashed because it looks for thumbnail as image to render (?!)

Possible Solution

image should be configurable.

Steps to reproduce

1. Create customQueries with a valid GraphQL query, without thumbnail
2. Run the app
