Event type with slug ${body.eventTypeSlug} belonging to user

Error message

Event type with slug ${body.eventTypeSlug} belonging to user ${body.username} within organization ${body.organizationSlug} not found.

What it means

Thrown by handleEventTypeToBeBookedNotFound when the booking body contains username + eventTypeSlug + organizationSlug and no matching org-scoped user event type was found. NotFoundException (HTTP 404). This is the organization-aware variant of error 321 — the resolver checked within the org namespace and missed.

Solutions

1. Confirm membership: GET /v2/organizations/{organizationSlug}/memberships for the user before booking.
2. Validate the event type exists within the org via the org-scoped event-types endpoint.
3. Drop organizationSlug if the event type is actually a non-org user event type (lets the 321 branch resolve).
4. Switch to teamSlug if the event type is now team-owned within the org.

Example fix

// before
body: { username: 'alice', eventTypeSlug: 'intro', organizationSlug: 'old-co' }

// after
body: { username: 'alice', eventTypeSlug: 'intro', organizationSlug: 'new-co' }

const { username, eventTypeSlug, organizationSlug } = body;
if (username && eventTypeSlug && organizationSlug) {
  const memberships = await api.get(`/v2/organizations/${organizationSlug}/memberships`);
  if (!memberships.data.some(m => m.user.username === username)) throw new Error('user not in org');
}

const hasOrgUserSlugCombo = (b: CreateBookingInput): boolean =>
  !!(b.username && b.eventTypeSlug && b.organizationSlug);

try { await api.post('/v2/bookings', body); }
catch (e) {
  if (e.response?.status === 404 && /within organization/.test(e.response.data.message)) {
    /* drop organizationSlug or correct it, then retry */
  } else throw e;
}

When it happens

Trigger: POST /v2/bookings with { username, eventTypeSlug, organizationSlug } where the user is not a member of that organization, the slug exists only outside the org, the org slug is wrong, or the event type is org-level but belongs to a different user within the org.

Common situations: User was removed from the organization but the client still caches the old org context; wrong organizationSlug after a tenant rename; event type was migrated to a team event type and is no longer user-scoped; cross-org confusion in multi-tenant integrations.
