Error message

result?.message||'Codex++ 会话读取失败'

What it means

Same guard as the userscript sync loop, but in tools/conversation-canvas/src/canvas-panel.js (the packaged panel). When readCanvasSource returns a non-ok result or nothing at all, it throws Error(result?.message || 'Codex++ 会话读取失败') so the sync rejects with the bridge's error message.

Solutions

  1. Match panel and host/bridge versions
  2. Read the underlying result.message and fix the root cause (missing file, permissions)
  3. Retry the sync or re-open the panel
  4. Show the failure in status and retain the last good canvas data
Defensive patterns

Strategy: try-catch

Validate before calling

if (!result || result.status !== 'ok') throw new Error(result?.message || 'Codex++ 会话读取失败');

Try / catch

catch(e){ status(`同步失败：${e.message}`); /* retain last rendered graph */ }

Prevention

When it happens

Trigger: Any sync in the panel where the session-read bridge reports {status:'error'} or resolves null/undefined — host absent, rollout file unreadable, request dropped.

Common situations: Panel running against an outdated Codex++ host; rollout jsonl missing for the requested thread; permissions or path errors inside the host reading the session file.
