Fixed in: 1.38.0

any-llm's Gemini provider builds call_{hash(function_call.name)}_{n} ids (providers/gemini/utils.py, non-stream and stream converters) and never reads FunctionCall.id, which google-genai exposes and Gemini sends. The ids also differ between processes because str hash() is salted. Reproduced on 1.33.0 and on main at 18ed82b. PR #1514 fixed the ids in 1.38.0 without linking this issue; the issue was closed on 2026-10-20.
