Solutions

1. Update/restart the dashboard so the parser fills defaults
2. Guard with (session.communications || []) — or remove the problematic session file
3. Check /api/sessions/:id output shape

Example fix

// before
communications: session.communications,
count: session.communications.length
// after
communications: session.communications || [],
count: (session.communications || []).length

const detail = await fetch(`/api/sessions/${id}`).then(r => r.json());
if (!Array.isArray(detail.communications)) fallbackToEmpty();

const hasComms = (s) => Array.isArray(s?.communications);

try { comms = await getComms(id); } catch { comms = { communications: [], count: 0 }; }

When it happens

Trigger: GET /api/sessions/:id/communications where the parser omitted the communications field (older session format or empty log).

Common situations: Sessions produced by an older CLI version lacking teammate messaging; partially written logs.
