  "details": "Graph API dropped legacy protocol features: root requests of the form GET /?ids=a,b (or /{version}/?ids=) return an error on v26.0+ since 2026-07-29 and on all supported versions from 2026-10-27. Meta does not state the error code.\n\nReplace each GET /?ids=... call with one request per object, or send the per-object requests in a single batch request (POST / with a batch parameter), and merge the results in your code.",
