Can't get torque map marker with relative path

[DSpada]

Hi,

I have a windshaft service and I need to get torque map but the marker based on a relative path doesn't works.
In the root folder I have a images folder whit some images.

{
"type": "torque",
"options": {
"cartocss_version": "2.0.0",
"sql": "SELECT geometry FROM mytable",
"cartocss":"
Map
{
-torque-frame-count:1;
-torque-animation-duration:10;
-torque-time-attribute:'total_count';
-torque-aggregation-function:'sum(total_count)';
-torque-resolution:2;
-torque-data-aggregation:linear
}
#table_2_point
{
image-filters:colorize-alpha(blue,cyan,lightgreen,yellow,orange,red);
marker-file:url('./images/torque_marker.png');
marker-width: 4;
marker-fill-opacity: 0.3*[value];
[zoom > 6]
{
marker-width: 6;
marker-fill-opacity: 0.4*[value];
}
[zoom > 7]
{
marker-width: 9;
marker-fill-opacity: 0.4*[value];
}
}
"
}
}

I alway get the error: Couldn't get marker-file ./images/torque_marker.png

Thanks,
Daniele

The marker-file must be a valid URL, for example, https://s3.amazonaws.com/com.cartodb.users-assets.production/maki-icons/circle-stroked-18.svg

But with mapnik type, relative path works fine:

{ 
        "type": "mapnik",
        "options":
        {
          "cartocss_version": "2.0.0",
          "sql": "SELECT geometry FROM mytable2",
          "cartocss": "#MyMapnikMap
          {
            ::main
            {
              marker-file: url('./images/myMapnikMarker.png');    
              marker-width: 6;            
              marker-fill:#00B050;
              marker-allow-overlap: true;   
              marker-line-opacity: 0; 
        
              [zoom<20]  {marker-width: 4;} 
              [themevalue = 38] {marker-fill:#F44611;}
              [themevalue = 39] {marker-fill:#FFFF00;}
              [themevalue = 40] {marker-fill:#00B050;}
              [themevalue = 41] {marker-fill:#7030A0;}
              [themevalue = 42] {marker-fill:#FF0000;}
              [themevalue = 43] {marker-fill:#FFFF00;}
            }

          }"
        }
      }

if one works why doesn't the other work?
