Parameter "expand_tasks" on List job runs request seams not to be working (databricsk api)

[Mildred]

I'm setting it as True, but it doesn't return the cluster_instance info. 

Here is the function I'm using:

def get_job_runs(job_id):
    """
    Fetches job runs for a specific job from Databricks Jobs API.
    """
    headers = {
        "Authorization": f"Bearer {DATABRICKS_TOKEN}",
        "Content-Type": "application/json"
    }

    url = f"{DATABRICKS_HOST}/api/2.2/jobs/runs/list"
    data = {
        "job_id": job_id,
        "expand_tasks": True
    }

    try:
        response = session.get(url, headers=headers, params=data, verify=False)
        response.raise_for_status()
        response_data = response.json()
        runs = response_data.get("runs", [])
        return runs

    except requests.exceptions.RequestException as e:
        print(f"Error during request: {e}")
        return []
    except json.JSONDecodeError as e:
        print(f"Error decoding JSON response: {e}")
        return []
    except Exception as e:
        print(f"An unexpected error occurred: {e}")
        return []

One of the returned items:
