+# `FacebookBadObjectError` occurs in FB SDK when it fetches an inconsistent or corrupted data.
+# It still has http status 200 but the object can not be constructed from what was fetched from API.
+# Also, it does not happen while making a call to the API, but later - when parsing the result,
+# that's why a retry is added to `get_results()` instead of extending the existing retry of `api.call()` with `FacebookBadObjectError`.
