JS Error "Cannot read property 'message' of undefined"

Hi everyone.
I'm trying to render table in unusual way and it fails with the exception: "Cannot read property 'message' of undefined"
Quantity of columns depends of variables

data in var revise_data

JS Code

$.ajax({
    url:'projects_orders_revise/table',
    method: 'GET',
    data: {
        'from':     function(){ return $('#from_d').val() },
        'to' :        function(){ return $('#to_d').val() },
        'project': function(){ return $('#project_id').val() }
    },
    success: function(data){
        revise_data = data.table;
        revise_columns = Array();

        $('#rtable_cols').html('');
        for(i in revise_data[0]){
            revise_columns.push({data:String(i)});
            $('#rtable_cols').append('<th>'+ i +'</th>');
        }
        render_table(revise_data, revise_columns);
    }
})

function render_table(revise_data, columns){
    revise = $('#rtable').DataTable({
        searching: true,
        serverSide: false,
        pageLength: 50,
        processing: true,
        ajax: revise_data,
        columns: _columns_
    })
}

What i'm doing wrong?

This works fine:

$('#rtable').DataTable({
        searching: true,
        serverSide: false,
        pageLength: 50,
        processing: true,
        ajax: {
                 url:'projects_orders_revise/table',
                 method: 'GET',
                 data: {
                          'from':     function(){ return $('#from_d').val() },
                          'to' :        function(){ return $('#to_d').val() },
                          'project': function(){ return $('#project_id').val() }
                 },
        },
        columns: revise_columns *

*data in variable revise_columns same as columns in the previuos code

Sorry for my English

And answer is:

replace ajax: by data:
