Hello , so i’m setting up automated instagram posting between airtable and buffer. All scenario runs well except for the image part. When I put my image link under “link to an image” and run it, it shows error says my " error. 400: Picture parameter passed without thumbnail parameter", but then when i place the same url link for thumbnail, it shows" error. 400: The provided image does not appear to be valid." the image is 1080x1080 , typical instagram image, documentation also didn’t specify what thumbnail is for a photo post, can anyone help?
