Process exited unexpectedly: EEXIST: file already exists,

[iuyaa]

What version of HAPI is running?

0.17.2

What platform is your computer?

runner: win11x64 25H2; hub: Linux 6.8.0-107-generic x86_64 x86_64

What issue are you seeing?

Process exited unexpectedly: EEXIST: file already exists, mkdir 'D:\Temp'

What steps can reproduce the bug?

我在我的vps上运行hapi hub 监听我的vps公网ip，在我的windows上配置了HAPI_API_URL和CLI_API_TOEKN指向我的vps。然后运行了hapi runner start注册成功。通过hapi开启会话可以从web界面看到。但是从web发送消息会提示Process exited unexpectedly: EEXIST: file already exists, mkdir 'D:\Temp'

What is the expected behavior?

web会话正常交互

这个报错是在 Windows runner 侧启动远程会话时产生的，不是在 Linux hub 侧。代码里没有找到硬编码的 D:\Temp；这个路径更可能来自 Windows runner 的会话目录输入、环境变量 TEMP/TMP，或被启动的 agent 自身输出。

已确认的启动链路：Web 新建会话会把 directory、agent、sessionType 发到 hub；hub 再通过 spawn-happy-session RPC 转给对应机器；Windows runner 会先检查/必要时创建目录，然后启动一个 detached 的 hapi ... --hapi-starting-mode remote --started-by runner 子进程。若子进程在 session webhook 前退出，runner 会把捕获到的 stderr 作为 “Process exited unexpectedly” 返回。

Relevant code:

• web/src/components/NewSession/index.tsx:285 - Web 发起 spawnSession，包含 machineId、directory、agent、sessionType。
• hub/src/web/routes/machines.ts:54 - Hub 的 /api/machines/:id/spawn 调用 engine.spawnSession(...)。
• hub/src/sync/rpcGateway.ts:137 - Hub 通过机器 RPC spawn-happy-session 转发启动请求。
• cli/src/api/apiMachine.ts:249 - Windows runner 注册并处理 spawn-happy-session。
• cli/src/runner/run.ts:246 - runner 检查目标目录是否存在。
• cli/src/runner/run.ts:263 - 目录不存在时 runner 调用 fs.mkdir(directory, { recursive: true })。
• cli/src/runner/run.ts:354 - Codex 且带 token 时，会在 os.tmpdir() 下创建临时 CODEX_HOME。
• cli/src/runner/run.ts:402 - runner 启动实际 HAPI 子进程，cwd 为目标目录。
• cli/src/runner/run.ts:467 - 子进程提前退出时，runner 会把 stderr tail 拼进错误信息。

Need more info:

• Web 新建会话时选择的是哪个 agent：Claude / Codex / Cursor / Gemini / OpenCode？
• 新建会话表单里的目录字段完整填写值是什么？
• Windows runner 上 hapi runner logs 的最新日志里，失败前后的相关几行。
• Windows runner PowerShell 中这两个检查的输出：Get-Item Env:TEMP,Env:TMP 和 Get-Item D:\Temp | Format-List FullName,PSIsContainer,Attributes。
