JS SDK getQueues() only returns queues from default division

We’re building a dashboard to track service levels across the board, but the Platform SDK for JavaScript seems stuck on our main division. I’m using the routingApi.getQueues() method in a Node.js script, passing in the standard OAuth token. It works, but it only spits out queues from the default org division. We have three other divisions set up for different regions, and those queues are missing completely from the response. The docs mention a divisionId parameter, but it’s optional, and leaving it blank should theoretically return everything or at least ask for clarification. Instead, it just defaults. Here’s the snippet I’m running:

const apiInstance = new _routing.RoutingApi();
apiInstance.getQueues({
 divisionId: undefined,
 pageSize: 250
}).then((data) => {
 console.log(data.entities);
}).catch((error) => {
 console.error(error);
});

Is there a specific flag I’m missing to force a cross-division search, or do I have to manually fetch the division IDs first and loop through them? I’ve tried hardcoding one of the other division IDs, which works for that specific slice, but that feels like a hack for a global view. I need all queues in one go.
