Integration called without owner data

Error message

Integration called without owner data

What it means

Intended guard for the roomCreated event: mapEventArgsToData builds the webhook payload from the room owner (user_id, user_name, owner object), and warns then skips the POST when owner is missing. Note that the earlier !room || !message guard in the same function usually fires first for roomCreated, because that event never carries a message (see error 1954).

Solutions

1. Emit roomCreated with its full signature: (event, owner, room)
2. Check the debug line 'Got the event arguments for the event' - a missing userId indicates the owner did not arrive
3. For dependable webhooks use sendMessage events, which carry full context
4. Patch the upstream guards in a fork if roomCreated deliveries are a hard requirement

// Defensive emission: only fire when the payload is complete
if (event === 'roomCreated' && owner && room) {
  executeTriggers('roomCreated', owner, room);
}

const hasOwner = (args: { owner?: IUser }): args is { owner: IUser } => !!args.owner;

When it happens

Trigger: executeTriggers invoked for roomCreated with fewer than the expected three arguments (event, owner, room), leaving argObject.owner undefined - e.g. custom emission code with wrong arity.

Common situations: Custom forks emitting roomCreated with missing or mis-ordered arguments; refactors that changed the emission signature without updating this consumer.
