How to add test case id to the test run?

Hello,

I'm using the Request Body to POST test run record ("projects/{project_id}/test-runs/record").

But for some reason I see only TestStepId but now TestCaseId in the output.

However, if I do it manually then I can see both.

What am I missing in my Body Request?

start_time =    datetime.datetime.now().isoformat()
end_time =      datetime.datetime.now().isoformat()
body = {
    "StartDate":  start_time,
    "EndDate":    end_time,
    "TestCaseId":222222,
    "TesterId": 111,
    "ReleaseId":5555,
    "ExecutionStatusId":2,
    'RunnerName': 'Name Surename',
    'ProjectId': project_id,
    'ArtifactTypeId': 2,
    'RunnerTestName': 'Test Name!',
    "TestRunSteps": [
        {
        'Position': 1,
        "TestStepId": 333337,
        "TestCaseId":222222,
        'ProjectId': 112,
        "ExecutionStatusId": 2,
        "Description": "info goes here",
        "ActualResult": "result goes here",
        'ArtifactTypeId': 7,
        },
        {
        'Position': 2,
        "TestStepId": 333338,
        'ProjectId': 112,
        "TestCaseId":222222,
        "ExecutionStatusId": 2,
        "Description": "info goes here",
        "ActualResult": "result goes here",
        'ArtifactTypeId': 7,
        }
    ],
}
RUNNER_LINK = f"https://some_comapmy.com/SpiraTest/Services/v7_0/RestService.svc"
POST_TEST_RUN = f"projects/{project_id}/test-runs/record"
tr_record_url = f'{RUNNER_LINK}/{POST_TEST_RUN}'
request = requests.post(tr_record_url, data=json.dumps(body), params=params, headers=headers)
request.content
