API Error : INVALID_DOCUMENT

I have been trying for months to fix this error I get everytime I try to publish with the app.

There has been an error with the API:
INVALID_DOCUMENT – Unsupported resource with URL=/wp-content/uploads/2017/02/NBC-This-Is-Us-AboutImage-1920×1080-KO.jpg (keyPath components->0->components->0->URL)
INVALID_DOCUMENT – Unsupported resource with URL=/wp-content/uploads/2017/02/NBC-This-Is-Us-AboutImage-1920×1080-KO.jpg (keyPath metadata->thumbnailURL)

I have disabled every single app and still get the error. I spoke to my host company and they tell me they do not remove the URl from the code.

I have two sites and get the same error on both sites. The one similarity is both sites use Cherry Framework.

Is there any way to hard code the URL in rather than have it try to find it and have this error every time?
