Pagination not working in detailed report API

Hi, I’m trying to get grouped time trackings using the Time Entries Detailed Report, but seems that pagintation isn’t working as I expect…

URL:{workspaceId}/reports/detailed (with workspace Id filled correctly) with this params in the request body:

    "amounts": null,
    "amountShown": "HIDE_AMOUNT",
    "dateRangeStart": "2023-10-01T00:00:00.000Z",
    "dateRangeEnd": "2023-12-31T23:59:59.999Z",
    "detailedFilter": {
        "page": 1,
        "pageSize": 50,
        "sortColumn": "DATE"
    "exportType": "JSON",
    "rounding": false,
    "sortOrder": "DESCENDING",
    "summaryFilter": {
        "groups": [
        "sortColumn": "GROUP"
    "userLocale": "it-IT",
    "users": {
        "ids": [
    "withoutDescription": false

The response Json has 71 records, but whatever I choose “page” & “pageSize” I always get the whole 71 record in response. What I’m doing wrong?
