Changelog Entry

Description

  • [Concisely describe the changes made in this pull request, including any relevant motivation and impact (e.g., fixing a bug, adding a feature, or improving performance)]

Fixes #12646

when processing streamed responses, the current logic uses the sequential index of a tool_calls item within the stream chunk to determine its corresponding index in the final aggregated tools list. This leads to a tool server error if the indexing of tool_calls in the stream does not begin at 0

Added

  • [List any new features, functionalities, or additions]

Changed

  • [List any changes, updates, refactorings, or optimizations]

Deprecated

  • [List any deprecated functionality or features that have been removed]

Removed

  • [List any removed features, files, or functionalities]

Fixed

  • [List any fixes, corrections, or bug fixes]
    Instead of relying on the stream chunk's index, it verifies that the index field from the incoming tool call object matches the index field of the target tool object already present in the final aggregated list. This ensures correct mapping regardless of the starting index in the streamed tool_calls.

Security

  • [List any new or updated security-related changes, including vulnerability fixes]

Breaking Changes

  • BREAKING CHANGE: [List any breaking changes affecting compatibility or functionality]

Additional Information

  • [Insert any additional context, notes, or explanations for the changes]
    • [Reference any related issues, commits, or other relevant information]

Screenshots or Videos

  • [Attach any relevant screenshots or videos demonstrating the changes]
