Range Filter: Reduce of empty array with no initial value

I have added the range_filter plugin to my DataTable

$.fn.dataTable.ext.search.push(
    function( settings, data, dataIndex ) {
        var min = parseInt( $('#min').val(), 10 );
        var max = parseInt( $('#max').val(), 10 );
        var ooh = parseInt( data[7] ) || 0; // use data for the ooh column
 
        if ( ( isNaN( min ) && isNaN( max ) ) ||
             ( isNaN( min ) && ooh <= max ) ||
             ( min <= ooh   && isNaN( max ) ) ||
             ( min <= ooh   && ooh <= max ) )
        {
            return true;
        }
        return false;
    }
);

However, when I filter, I see this in the console:

Uncaught TypeError: Reduce of empty array with no initial value

How do I address this issue?

Update: Console is finding an error in my summation code where ".reduce" is when i place a value inside the "min" "max" filters

// Total DEC over current page
            if (api.column( 6 ).data().length){
                var decTotal = api
                    .column( 6, { page: 'current'} )
                    .data()
                    .reduce( function (a, b) {
                        return intVal(a) + intVal(b);
                    } ) }
                else{ decTotal = 0};
