Your Extension is attempting to load external files, either from a CDN or other private server, and this will cause your Extension to not function in production. Please make sure that all files that are required by your Extension to function are included in your upload.
How do I load images for an extension if not from a CDN? I can’t include these images in the files I upload to twitch as the images won’t be known at the time of publication. If this is a policy violation how is it that other apps (like twitter feed and instagram feeds) can load external images?
