SDK crashes on response.output_item.done for missing item

[devpras22]

The @openai/realtime-api-beta SDK crashes when it receives a response.output_item.done event for an unknown or missing item ID. Instead of checking if the item exists in its internal map, the SDK immediately tries to access properties like item.tool, item.status, or item.event_id, causing a fatal error.

Here’s the stack trace:

Error: response.output_item.done: Item "item_BLqSTfYRcIduLcytDILia" not found
    at response.output_item.done (/node_modules/@openai/realtime-api-beta/lib/conversation.js:171:15)

This crash kills the entire server. The SDK should gracefully skip missing item_ids or log a warning, but currently does neither. Please fix this as it’s blocking production use of the Realtime API.
