Solutions

1. Provide a non-empty incident.content string before emitting postIncident.
2. Validate both title and content client-side and block submission otherwise.
3. Use the exact field name 'content'.

Example fix

// before
socket.emit("postIncident", slug, { title: "Outage", content: "" }, cb);
// after
socket.emit("postIncident", slug, { title: "Outage", content: "Investigating degraded API." }, cb);

function validIncidentContent(i) {
  return i && typeof i.content === "string" && i.content.trim() !== "";
}
if (!validIncidentContent(incident)) throw new Error("Please input content");
socket.emit("postIncident", slug, incident, cb);

function hasIncidentContent(i) {
  return i != null && typeof i === "object" && typeof i.content === "string" && i.content.trim() !== "";
}

try { await emitAsync("postIncident", slug, incident, cb); }
catch (e) { if (/input content/.test(e.message)) flagField("content"); else throw e; }

When it happens

Trigger: postIncident is emitted with an incident whose title passes but content is falsy or trim() === ''.

Common situations: User fills the title but not the message; whitespace-only content; client sends a content field named differently (e.g. 'body', 'text').
