Codex++ 会话读取失败

Error message

Codex++ 会话读取失败

What it means

Same guard as error 611 in the panel bundle: when /session/export via the bridge resolves without status:'ok' and the message is not an export-size error, readCanvasSource throws the bridge message or this generic failure string.

Solutions

1. Retry via refresh — export failures can be transient
2. Verify the session exists and the id is correct
3. Update Codex++/userscript after Codex app updates
4. Inspect DevTools console/network for the failing /session/export response

if(result?.status!=='ok'&&!isExportSizeError(result?.message)){console.warn('export failed',result);return retry();}

const exportOk=(r)=>r!=null&&r.status==='ok';

try{const r=await bridge('/session/export',{session_id:id});}catch(e){if(!isExportSizeError(e.message))notifyUser('会话读取失败，请刷新重试');}

When it happens

Trigger: Bridge export returned an error/empty result whose message fails isExportSizeError — backend export failure, unknown session, or changed response schema.

Common situations: Codex backend error on export; session deleted mid-view; version mismatch between panel script and Codex backend causing unexpected payload.
