I’m getting this exact same error as well after patching to the new server version.
[Req#1f71] SQLITE3:0x7ff7cbba7300, 1, no such column: media_items.begins_at in “select metadata_items.id from metadata_items join metadata_items as parents on parents.id=metadata_items.parent_id join metadata_items as grandparents on grandparents.id=parents.parent_id where metadata_items.library_section_id in (2) and metadata_items.metadata_type=4 order by media_items.begins_at asc, metadata_items.id asc, media_items.width desc, metadata_items.originally_available_at asc, media_parts.id asc”
