When does this happen?
IF Multi-step agentic tool calling on Vertex AI Gemini 3 models fails, returning zero function calls due to incorrect thoughtSignature replay, parallel call grouping, session overlap, and silent timeouts.
How others solved it
THEN Upgrade to NeuroLink v9.49.0+ which ensures correct thoughtSignature replay as a sibling field on each functionCall part, groups parallel tool calls by stepIndex, enforces a 5-minute timeout, surfaces silent timeouts as TimeoutError, and uses an executionId per invocation to prevent session overlap.
