Error message
Failed to publish agent flow: ${error.message} What it means
Community Hub publisher for Agent Flows. The modal builds a payload (name, description, steps, tags, visibility) and calls CommunityHub.createAgentFlow; on success:false the API's error string is rethrown, caught, and shown as a toast with the raw error.message appended after the colon. The generic prefix therefore always carries the specific backend reason with it.

Solutions
- Read the full toast / console.error — the text after the colon is the API's actual rejection reason
- Confirm you are authenticated to the Community Hub (connection/settings) and retry
- Shorten the flow: fewer steps or smaller step configs if the serialized flow is very large
- Fill every required form field (name, description) and ensure tags are valid before submitting
Defensive patterns
Strategy: try-catch
Validate before calling
function validFlowPayload(form, entity, tags) {
const name = form.get("name")?.trim();
const description = form.get("description")?.trim();
if (!name || !description) return { ok: false, reason: "name and description are required" };
if (!entity?.steps?.length) return { ok: false, reason: "flow has no steps" };
if (JSON.stringify(entity.steps).length > MAX_FLOW_BYTES) return { ok: false, reason: "flow too large" };
return { ok: true };
} Try / catch
catch (error) {
console.error("Failed to publish agent flow:", error);
showToast(`Failed to publish agent flow: ${error.message}`, "error", { clear: true });
if (/unauthor|401|session/i.test(error.message)) openCommunityHubLogin();
} Prevention
- Validate required fields client-side before calling createAgentFlow so API rejections are rare
- Keep hub session state checked — most publish failures are auth-related
- Cap flow payload size before stringify to avoid oversized-request failures
When it happens
Trigger: createAgentFlow rejects: missing/invalid fields (empty name or description), steps failing server-side validation, flow JSON too large, duplicate published item name, Community Hub session missing/expired, or a backend/network failure (non-2xx).
Common situations: Publishing while not signed in to the Community Hub; very long step payloads making JSON.stringify(steps) huge; hub API changed after an upgrade; transient outage or rate limiting of the hub.
