Analytics API paging pageCount returns 1 instead of total pages

We are using the genesyscloud-node-sdk to fetch conversation aggregates with paging. The code looks like this:

const response = await analyticsApi.postAnalyticsConversationsAggregates({
 body: {
 paging: { pageSize: 10, pageNumber: 1 }
 },
 // other filters...
});
console.log(response.paging.pageCount); // Returns 1

The pageCount is always 1 even though we know there are 50 pages of data. The total field in the paging object is correct but pageCount is not calculated. Is this a known issue with the SDK or the API? We are on SDK version v1.0.123.
