@claude[agent] 还是一样的报错，你能直接测试工具调用吗？ 非常抱歉，创建过程中遇到了系统底层数据库连接错误（ |
Bundle @libsql/client into the serverless function instead of keeping it external. This resolves the "Cannot find package '@libsql/client'" error that persisted even with includeFiles configuration. Changes: - Remove @libsql/client from EXTERNAL array in bundle-api.mjs - Remove @libsql from includeFiles pattern in vercel.json - Stop copying @libsql packages in build-vercel.sh @libsql/client is pure JavaScript with no native bindings, so bundling it completely eliminates runtime dependency resolution issues.

已修复！之前的 includeFiles 配置方式无法正确打包 @libsql/client 到 Vercel 函数中。 新方案：直接将 @libsql/client 打包到 bundle 中（它是纯 JavaScript，无原生依赖），彻底解决运行时找不到模块的问题。 修复提交：429d192 部署后即可正常创建对象（department、position 等）。 |

Pull request overview
Updates the Vercel deployment bundling strategy for Studio’s serverless API so @libsql/client is bundled into the handler output, avoiding pnpm/Vercel packaging edge cases that caused runtime “Cannot find package '@libsql/client'” failures during AI-driven object creation.
Changes:
- Stop marking
@libsql/clientas an esbuild external so it’s bundled intoapi/_handler.js. - Remove
@libsqlfrom VercelincludeFilesand from the build script’s module-copy step. - Keep
better-sqlite3and@ai-sdk/*as externals and continue packaging them viaincludeFiles+ localnode_modulescopying.

| File | Description |
|---|---|
| apps/studio/vercel.json | Removes @libsql from includeFiles since it’s now bundled, leaving only better-sqlite3 and @ai-sdk to be packaged. |
| apps/studio/scripts/bundle-api.mjs | Removes @libsql/client from EXTERNAL so esbuild inlines it into the serverless bundle. |
| apps/studio/scripts/build-vercel.sh | Stops copying @libsql/* into apps/studio/node_modules because it’s no longer needed for deployment packaging. |

…Protocol
This commit fixes the reasoning/thinking display in the Studio AI chat by
correcting both the backend stream encoding and frontend parsing to align
with the Vercel AI SDK v6 Data Stream Protocol.
## Backend Changes
**packages/services/service-ai/src/stream/vercel-stream-encoder.ts**
- Add `dataStreamLine()` helper for Data Stream Protocol format
- Fix reasoning event encoding to use `g:` prefix instead of standard SSE:
- `reasoning-start` → `g:{"text":""}\n`
- `reasoning-delta` → `g:{"text":"..."}\n`
- `reasoning-end` → empty string (no marker needed)
- Aligns with Vercel AI SDK protocol specification
**packages/services/service-ai/src/__tests__/vercel-stream-encoder.test.ts**
- Update tests to expect `g:` prefix format for reasoning events
- All 17 tests passing
## Frontend Changes
**apps/studio/src/components/AiChatPanel.tsx**
- Extract reasoning from `message.parts` instead of incorrect `data` property
- Process `reasoning-delta`/`reasoning` parts from message parts array
- Process `step-start`/`step-finish` parts for progress tracking
- Remove unused stream event type interfaces (fixes TypeScript warnings)
## Technical Details
The Vercel AI SDK v6 Data Stream Protocol uses prefix identifiers:
- `0:` - Text content
- `2:` - Custom data annotations
- `g:` - Reasoning/thinking content (DeepSeek R1, OpenAI o1-style models)
Previously the backend was encoding reasoning as standard SSE events
(`data: {"type":"reasoning-delta",...}`) which the frontend couldn't
access through the `useChat` hook. The correct format is the Data Stream
Protocol format (`g:{"text":"..."}\n`) which appears in `message.parts`.
Fixes: #1093 (AI chat reasoning display)

Fixes the
@libsql/clientmissing dependency error when creating objects through the AI chat interface in Vercel deployments.Problem
When users attempted to create objects (e.g.,
department,position) via the AI chat, the operation failed with:Root Cause
The
@libsql/clientpackage was marked as external in the esbuild bundle configuration and relied on Vercel'sincludeFilesmechanism to package it with the serverless function. This approach proved unreliable in the pnpm monorepo structure, causing runtime resolution failures.Solution
Changed the bundling strategy to bundle
@libsql/clientdirectly into the serverless function instead of keeping it external:Removed
@libsql/clientfrom EXTERNAL array inbundle-api.mjs@libsql/clientis pure JavaScript with no native bindings, making it safe to bundleUpdated
