Initialization datatable via Ajax - No data displayed - ajax

Question

I have a datatable that I would like to initialize with an Ajax call http://url/api/v1/shocks
table.blade.php
<div class="card-body p-0">
<div class="table-responsive">
<table class="table table-striped table-md" id="table-raw-shocks" width="100%" cellspacing="0">
<thead>
<tr>
<th>Record Id</th>
<th>Count</th>
<th>Date</th>
<th>Amplitude 1 (G)</th>
<th>Amplitude 2 (G)</th>
<th>Time 1 (s)</th>
<th>Time 2 (s)</th>
<th>Freq 1 (Hz)</th>
<th>Freq 2 (Hz)</th>
</tr>
</thead>
<tfoot>
<tr>
<th>Record Id</th>
<th>Count</th>
<th>Date</th>
<th>Amplitude 1 (G)</th>
<th>Amplitude 2 (G)</th>
<th>Time 1 (s)</th>
<th>Time 2 (s)</th>
<th>Freq 1 (Hz)</th>
<th>Freq 2 (Hz)</th>
</tr>
</tfoot>
</table>
</div>
</div>
Javascript part
$(document).ready(function () {
initShocksActivityTable();
});
function initShocksActivityTable() {
var url = '{{ route("api:v1:shocks.index") }}'; //http://url/api/v1/shocks
var table = $('#table-raw-shocks-all').DataTable({
responsive: true,
responsive: {
details: {
type: "column",
target: "tr"
}
},
orderCellsTop: true,
fixedHeader: true,
dom: "Bfrtip",
buttons: ["copy", "csv", "excel", "pdf", "print"],
columnDefs: [{
sortable: true
}],
"ajax": url,
"columns": [{
"data": "attributes.record_id"
},
{
"data": "attributes.count"
},
{
"data": "attributes.date_time"
},
{
"data": "attributes.amplitude_1"
},
{
"data": "attributes.amplitude_2"
},
{
"data": "attributes.time_1"
},
{
"data": "attributes.time_2"
},
{
"data": "attributes.freq_1"
},
{
"data": "attributes.freq_2"
},
],
lengthMenu: [
[10, 25, 50, -1],
[10, 25, 50, "All"]
],
iDisplayLength: 10,
order: [
[2, "desc"]
]
});
}
My data looks like this :
Attributes contains all the necessary data that I would like to add on my datatable.
When I do that, I have no data displayed. I suspect that it is because, my data is an array ( [0], 1...)
I tried to add this piece of code (https://datatables.net/reference/option/ajax.dataSrc)
"dataSrc": "data.attributes"
But it still does not work.
I'm sure, it's something that I missed but I have some difficulties to find what is the problem to fetch correctly the data.
Could you please help me on that ? Thank
