ADK >=2.2.0 unconditionally sets part_metadata on genai Parts via the A2A converter, but the google-genai SDK rejects it on Vertex AI (Developer API only). Add a before_model_callback that clears part_metadata when running in Vertex AI mode. TODO: revert this workaround once the upstream ADK fix lands (part_metadata should not be set when using Vertex AI backend). Track: https://github.com/google/adk-python/issues Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
