refine x supabase: file upload issue

Hi, I'm trying to add a video upload section in my project, but I keep getting the error in the attached image whenever I try to save a record after successfully uploading the video. Mind you, I'm following the tutorial in the documentation : https://refine.dev/docs/packages/documentation/data-providers/supabase/#adding-an-edit-page. But I can't seem to get it to work.
