Changelog Entry

Description

  • Fixes a bug in stream_body_handler with tool calls. Previously if the first chunk of an object in tool_calls is incomplete (e.g. the ["function"]["arguments"] key is missing), subsequent updates to it will raise a KeyError. This bug affects some models when using native tool calls.

Fixed

  • Error when handling native tool calls with streaming.
