Error message

detail || `HTTP ${res.status}`

What it means

Thrown by _chatAboutResearch in research/panel.js when POST /api/research/spinoff/{researchId} fails. The client attempts to extract a FastAPI-style detail from the JSON body; if absent or unparseable it falls back to the bare HTTP status. The catch re-enables the button and alerts, so UI state is restored.

Solutions

1. Close and reopen the research panel to refresh ids, then retry.
2. Read the detail in the alert for the server's reason; check server logs for 5xx.
3. Re-authenticate if the status is 401.
4. Verify the research entry still exists in the panel list.

if (!researchId) { btn.disabled = false; return; }

const isSpinoffPayload = (p) => !!p && !!p.session_id;

try { ... } catch (e) { btn.disabled = false; btn.innerHTML = origLabel; alert('Could not start follow-up chat: ' + e.message); }

When it happens

Trigger: Creating a follow-up chat from a research report whose id no longer exists (404); research data deleted between panel open and click; server cannot create the spinoff session (db error → 500 with detail); auth expired (401 with empty body → 'HTTP 401').

Common situations: Stale research panel left open while the server restarted or the research store was cleared; long-lived tabs with expired sessions.
