My Question or Issue
I am making a program using the spotify api, it collects songs from the api itself and I would like to obtain the video thumbnails that some songs have and are shown in the mobile version of spotify, but it happens that when viewing the data returned by the spotify api each song always appears video_thumbnail: {url: null}
Is it simply because it cannot be obtained or is it because I need to make a query to the API or something else?
