Vew All tasks for Technician via APIv3 (powershell)

Hello!

I'm having some issues designing a process that would invovle reading all of the tasks assigned to a technician via the API.

When i attempt to use the api query designer in the documentation, i get the results that i would like -- All tasks owned by a particular technician, but when i copy either the code example or the JSON information and run from powershell, i receive what appears to be ALL tasks, and not the ones i'm searching for.

When i view the returned object i also note that none of the information i've placed in the JSON for the search, shows up under the list_info section of the return data:

#Powershell version - 5.1
$url = "https://XXXX/api/v3/tasks"
$technician_key = @{ 'authtoken' = 'XXX'}
$input_data = @'
{
    "list_info": {
        "row_count": "12",
        "start_index": "2",
        "get_total_count": "true",
        "sort_fields": [
            {
                "field": "title",
                "order": "asc"
            },
            {
                "field": "created_time",
                "order": "desc"
            }
        ],
        "filter_by": {
            "id": "1"
        },
        "search_criteria": {
            "field": "priority",
            "condition": "is not",
            "values": [
                {
                    "id": "1"
                }
            ],
            "children": [
                {
                    "field": "additional_cost",
                    "condition": "lte",
                    "values": [
                        100
                    ],
                    "logical_operator": "AND"
                },
                {
                    "field": "marked_owner.name",
                    "condition": "like",
                    "values": [
                        "Howard Stern"
                    ],
                    "logical_operator": "OR"
                }
            ]
        },
        "fields_required": [
            "id",
            "status",
            "additional_cost",
            "created_time"
        ]
    }
}
'@
$data = @{ 'input_data' = $input_data}
$response = Invoke-RestMethod -Uri $url -Method get -Body $data -Headers $technician_Key -ContentType "application/x-www-form-urlencoded"
$response

The above example is taken directly from the directions page, with the addition of 'get_total_rows' When run from the API Directions page, i get total count of 244, when run from powershell or python i get the total count of all tasks in the system (over 10k).

I can also see that in th returned information the list_info does not contain any of the filter, or search information as it does on the documentation page:

has_more_rows   : True
start_index     : 1
end_index       : 100
get_total_count : False
row_count       : 100

Is there an error in my code above or something i'm missing? Does anyone have any suggestions on how i can move foward with retreiving all Tasks assigned to a technician?

Thank you!
