I am using the graph API to get the link data from the object_story_spec of a creative. This manifests as the following request: creative_url = f"{creative['id']}" creative_params = { "fields": "object_story_spec{link_data}", "access_token": access_token, } This works fine with a normally configured carousel ad. However, if I try to customize the ad for different placements as shown in the screenshot, I suddenly get an "Error calling Facebook Graph API: (#200) Permissions error". Anyone familiar to what I can do?
