new DataTable('#example', {
    columnControl: ['order', ['search', 'searchList']],
    ordering: {
        indicators: false,
        handler: false
    },
    stateSave: true
});

quick stupid fix > set null to undefined searchList in state

            stateSaveCallback: function (settings, data) {
                if (data.columnControl[0].searchList === undefined) {
                    data.columnControl = null;
                }
                localStorage.setItem(TABLE_STATE_KEY, JSON.stringify(data));
            },
