From 02a3a3c47cffbc076331e4f9c5778d9298e7b8d3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?F=C3=A9lix=20Malfait?= Date: Wed, 17 Jun 2026 18:12:21 +0200 Subject: [PATCH] fix(ai): handle dynamic-tool message parts in chat persistence (#21740) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixes #20558. AI chat streams crashed with `Unsupported part type: dynamic-tool` whenever the model emitted a *dynamic* tool call (a tool that isn't part of the bound schema). The assistant message never persisted, so the user saw a hard failure mid-stream. ## Root cause The AI SDK v6 emits two flavors of tool parts: - **Static** — `type: "tool-"` (e.g. `tool-execute_tool`) - **Dynamic** — `type: "dynamic-tool"`, with the name on `part.toolName` `mapUIMessagePartsToDBParts` recognised tool parts with a homegrown check: ```ts part.type.includes('tool-') && 'toolCallId' in part ``` That returns `false` for `'dynamic-tool'` (it contains `-tool`, not `tool-`), so dynamic parts fell through to `throw new Error(\`Unsupported part type: ${part.type}\`)` during the `handleStreamFinish` persistence step. Stack trace from the issue matches exactly. The same broken heuristic was duplicated in: - `packages/twenty-server/.../mapDBPartToUIMessagePart.ts` (reverse mapper) - `packages/twenty-front/.../utils/mapDBPartToUIMessagePart.ts` (frontend mirror — would also throw on a `dynamic-tool` row reloaded from history) Meanwhile, two other call sites in the codebase (`finalize-dangling-tool-parts.util.ts`, `isThinkingStepPart.ts`) already correctly use the SDK's `isToolUIPart`, which natively recognises both flavors. ## What this PR does 1. **Switches all three mappers to the SDK's canonical check** (`isToolUIPart` on the forward path; explicit `dynamic-tool` + `tool-` startsWith on the reverse paths, where the input is an entity/DTO, not a UI part). 2. **Persists `toolName`** — the column already existed on the entity, DTO and GraphQL fragment but nothing wrote it. For static parts the name is recoverable from `type`; for dynamic parts it's the only place the name lives, so without it the round-trip is impossible. The shared denormalisation also helps existing per-tool analytics (`count-native-web-search-calls-from-steps.util.ts`). 3. **Reconstructs `dynamic-tool` parts on read** (with `toolName`) so they survive a DB round-trip both on the server and on the frontend history view. 4. **Adds a round-trip unit test** covering both `dynamic-tool` and a static tool part to lock the behavior in. ## Architecture notes (called out for review) - `mapDBPartToUIMessagePart` is duplicated frontend + backend because the input shape differs (TypeORM entity vs. GraphQL DTO). Out of scope to consolidate here, but they're drifting — this PR is what that drift looked like in production. Worth a follow-up to express the shared logic once over a unified row type. - I left the existing renderer guard `part.type !== 'dynamic-tool'` in `AiChatAssistantMessageRenderer.tsx` alone — it's a reasonable UI-side decision to not attempt to render an unknown dynamic tool generically. Persistence and history reload now work; rendering of dynamic tool calls is a separate UX decision. - No DB migration needed — the `toolName` column already exists. Old static rows have `toolName: null`; the reverse mapper recovers their name from the `type` column as before. Old dynamic-tool rows don't exist (they all threw on write). ## Test plan - [x] `yarn workspace twenty-server jest map-message-parts.dynamic-tool` — 5 passed - [x] `yarn workspace twenty-server jest finalize-dangling-tool-parts.roundtrip` — still 4 passed (no regression) - [x] `yarn nx typecheck twenty-server` — clean - [x] `yarn nx typecheck twenty-front` — clean - [x] `yarn nx lint:diff-with-main twenty-server` — clean - [x] `yarn nx lint:diff-with-main twenty-front` — clean - [ ] Manual: trigger an AI chat that exercises a dynamic tool (e.g. via an MCP server returning a tool not in the bound schema) and confirm the stream finishes and the message persists. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_013EE11eVWtyxmdcbEHVJKoc --- _Generated by [Claude Code](https://claude.ai/code/session_013EE11eVWtyxmdcbEHVJKoc)_ Review in cubic --------- Co-authored-by: Claude --- .../AiChatAssistantMessageRenderer.tsx | 11 +- .../ai/components/ThinkingStepsDisplay.tsx | 6 +- .../ai/components/ToolStepRenderer.tsx | 8 +- .../AiChatAssistantMessageRenderer.test.tsx | 24 +++ .../ai/utils/mapDBPartToUIMessagePart.ts | 15 +- .../src/modules/ai/utils/thinkingStepPart.ts | 8 +- .../map-message-parts.dynamic-tool.spec.ts | 137 ++++++++++++++++++ .../utils/mapDBPartToUIMessagePart.ts | 11 +- .../utils/mapUIMessagePartsToDBParts.ts | 40 +++-- 9 files changed, 217 insertions(+), 43 deletions(-) create mode 100644 packages/twenty-server/src/engine/metadata-modules/ai/ai-agent-execution/utils/__tests__/map-message-parts.dynamic-tool.spec.ts diff --git a/packages/twenty-front/src/modules/ai/components/AiChatAssistantMessageRenderer.tsx b/packages/twenty-front/src/modules/ai/components/AiChatAssistantMessageRenderer.tsx index 7b246f4d4b..f348b0ce43 100644 --- a/packages/twenty-front/src/modules/ai/components/AiChatAssistantMessageRenderer.tsx +++ b/packages/twenty-front/src/modules/ai/components/AiChatAssistantMessageRenderer.tsx @@ -9,7 +9,7 @@ import { ToolStepRenderer } from '@/ai/components/ToolStepRenderer';
