Does the installer set a particular version of agent-server to run via `uv`?

I'm getting a bunch of errors, including
```18:39:56 [agent-server] KeyError: "ToolDefinition
18:39:56 [agent-server] 'canvas_ui' is not registered"```
which suggests it's using an old version of agent-server

You can set this with an environment variable last I looked

I've been using `OH_AGENT_SERVER_GIT_REF=main` in my .env

Which version are you running for canvas?

Agent server version is specified here: <https://github.com/OpenHands/agent-canvas/blob/main/config/defaults.json#L5>

any way I can check which agent-server version it got?

```{"uptime":69.0,"idle_time":69.0,"title":"OpenHands Agent Server","version":"1.24.0","sdk_version":"1.24.0","tools_version":"1.24.0","workspace_version":"1.24.0","build_git_sha":"unknown","build_git_ref":"unknown","python_version":"3.12.12 (main, Jan 13 2026, 17:48:58) [Clang 21.1.4 ]","usable_tools":["file_editor","task_tool_set","task","task_tracker","terminal","browser_tool_set","edit","list_directory","read_file","write_file","glob","grep","planning_file_editor"],"runtime_idle_timeout_seconds":null,"max_foreground_terminal_timeout_seconds":null,"docs":"/docs","redoc":"/redoc"}```

actually my working agent-server doesn't list that either

Are you resuming an older conversation that used this tool?

I also get
```   Failed to import module 'canvas_ui_tool' for tool 'canvas_ui': No module named 'canvas_ui_tool'```

which tells me it's not importing from the repo

we should really simplify that custom tool logic

I was still able to start a convo even with that error it seems
