Error message

Invalid Target Room

What it means

Thrown by _verifyRequiredFields when the chosen event uses a target room but the integration payload omits `targetRoom`. Only the userCreated event declares use.targetRoom = true, because new-user notifications must be posted somewhere other than the channel list, so a userCreated integration without targetRoom is rejected with Meteor.Error code 'error-invalid-targetRoom'.

Solutions

  1. Add targetRoom with the destination room name for userCreated integrations, e.g. targetRoom: 'announcements'
  2. Verify the room exists before saving so you do not just move the failure to delivery time
  3. Remember the rule: only userCreated needs targetRoom; the other six events do not

Example fix

// before
{ type: 'webhook-outgoing', event: 'userCreated', username: 'rocket.cat', urls: [...] }

// after
{ type: 'webhook-outgoing', event: 'userCreated', username: 'rocket.cat', targetRoom: 'announcements', urls: [...] }
Defensive patterns

Strategy: validation

Validate before calling

const eventsNeedingTargetRoom = ['userCreated'];
if (eventsNeedingTargetRoom.includes(event) && !integration.targetRoom?.trim()) {
  throw new TypeError('userCreated integrations require a targetRoom');
}

Prevention

When it happens

Trigger: POST /api/v1/integrations.create with type 'webhook-outgoing' and event 'userCreated' while targetRoom is absent, empty, or undefined in the payload.

Common situations: Teams wiring HR/onboarding bots to the userCreated event and forgetting the destination room; payloads copied from a sendMessage integration where targetRoom is not a field.
