I had a upload: true which creates filename, width, height, filesize, url field. I want to override the url because i want it to show in the admin panel. but got the error. Other fields work.

I also want to ask if there a way to remove THUMBNAIL_URL? i got this video collection which store mp4 and have a thumbnail relationship to media but i dont want that thumbnail_url. any way to remove it?
