I’m trying to create an Instagram Carousel with JPG images taken from a Google Drive folder but I get: The operation failed with an error. (#2) Service temporarily unavailable (2, OAuthException).
If you take a look at the notes in the instagram module you need to use a publicly accessible url for this. I would suggest using google cloud storage.
Review the instagram api docs for carousel images. Your going to need the correct JSON format under the files field.
