JSON question

Hi,

I have the following JSON Output:

    {
        "COLUMNS": ["ID", "RECIPIENT", "POLICY_ID", "PDF_ENABLED", "SMIME_ENABLED", "PGP_ENABLED", "DIGITAL_SIGN"],
        "DATA": [
            [1639, "user1@domain.tld", 33, 2, 2, 2, 2],
            [1046, "user2@domain.tld", 33, 1, 2, 2, 2],
            [1277, "user3@domain.tld", 33, 1, 1, 2, 2],
            [1051, "user4@domain.tld", 33, 1, 2, 2, 2],
            [1676, "user5@domain.tld", 33, 2, 2, 2, 2],
            [1615, "user6@domain.tld", 33, 2, 2, 2, 2],
            [1055, "user7@domain.tld", 33, 2, 2, 2, 2],
            [1056, "user8@domain.tld", 33, 2, 2, 2, 2],
            [1254, "user9@domain.tld", 33, 2, 2, 2, 2],
            [1264, "user10@domain.tld", 33, 1, 1, 2, 2],
            [1642, "user11@domain.tld", 49, 2, 2, 2, 2]
        ]
    }

How would I go about creating a table with that JSON data? Originally, I thought using the following would do it:

$(document).ready(function() {
    $('#sortTable').DataTable( {
      'processing': true,
      'serverSide': true,
      'ajax': './inc/get_int_recipients.cfm',
      'columns': [
        { 'data': 'id' },
        { 'data': 'recipient' },
        { 'data': 'policy_id' },
        { 'data': 'pdf_enabled' },
        { 'data': 'smime_enabled' },
        { 'data': 'pgp_enabled' },
        { 'data': 'digital_sign' },
    ],

However, as soon as I insert the "columns" code in the script in an attempt to map the columns, I get the following error in the browser console:

Uncaught TypeError: Cannot read property 'mData' of undefined
    at HTMLTableCellElement.<anonymous> (jquery.dataTables.min.js:104)
    at Function.each (jquery-3.6.0.min.js:2)
    at S.fn.init.each (jquery-3.6.0.min.js:2)
    at HTMLTableElement.<anonymous> (jquery.dataTables.min.js:104)
    at Function.each (jquery-3.6.0.min.js:2)
    at S.fn.init.each (jquery-3.6.0.min.js:2)
    at S.fn.init.u [as dataTable] (jquery.dataTables.min.js:97)
    at S.fn.init.l.fn.DataTable (jquery.dataTables.min.js:185)
    at HTMLDocument.<anonymous> (view_internal_recipients.cfm:125)
    at e (jquery-3.6.0.min.js:2)

If, I don't use the "columns" code in the script, the table is blank, i.e. no data. What am I doing wrong?

Thanks
