Description
ChatCitation object appears to have formerly been a dict type and is now object type. Thus, access patterns for attributes 'start', 'end' and 'document_ids' have changed.

Old access pattern:
citation['start']

yield an "object is not subscriptable" error

New access pattern:
citation.start

works as intended
