Hi! I’m trying to publish posts to Instagram via n8n using the Facebook Graph API node.
I’ve tried using image links from:
- Google Drive (uc?export=view&id=...)
- Direct links from ImgBB (ending in .jpg)
…but I still get this error:
(#100) image_url must be a valid URL pointing to a public image
These links work fine with Facebook, but not with Instagram.
Anyone managed to get image_url working for Instagram posts in n8n?
