Hello, I am getting the following error; I suspect it is in my JS code and has not reached the execution of the JSON returned (however I am attaching a valid response from the server). Any help appreciated. Thanks.

Error stack -

Here is my server-side JS :
$(document).ready(function() {
$('#lidarSaas').DataTable( {
"processing": true,
"serverSide": true,
"ajax": {
"url": "http://127.0.0.1:8000/lidarSaas/",
"dataType" :"json",
"dataSrc": "",
},
"columns": [
{ "data": "id" },
{ "data": "title" },
{ "data": "uploadTimestamp" },
{ "data": "uploadFileNameS3" },
{ "data": "processedTimestamp" },
{ "data": "processedFileNameS3" },
{ "data": "status" },
{ "data": "processingTime" },
{ "data": "owner" },
]
} );
} );

Here is my sample JSON (validated) -

    Answer ✓

    Looks like you defined 9 columns in Datatables but have 8 in the HTML. I think you need to define a column for id and hide it using columns.visible.

    Answer ✓

    For just not define it in the columns array. Just because it is in the data set doesn't mean you need to use it.
