A call to resource returns my source code!

I create a custom service and it shows up in my services configuration (see attached image). When I tested the URL http://localhost/services/seedme/ with Firefox Poster plugin, I actually get back "200 OK" along with the entire source code in my .inc file...the service is returning my source code! This is huge security hole and definitely not the desired behavior.

My service configuration:

• Server = REST
• Path to endpoint = services
• Debug mode disabled
• no session authentication
• REST response formatter: json, jsonp
• REST request parsing: application/json, application/x-www-form-urlencoded

This is my resource definition in my custom module:

function seedme_services_services_resources()
{
    $resources = array ( "seedme" => array (
        "create" => array ( "help" => "Create a new data set",
            "file" => array ( 'file' => 'inc', 'module' => 'seedme_services' ),
            "callback" => "seedme_services_create",
            'access callback' => 'user_access',
            'access arguments' => array ( 'create data set' ),
            /*
            "args" => array ( array (
                "name" => "data",
                "type" => "array",
                "description" => "The data set object",
                "optional" => FALSE ) ) 
            */
            ) ) );
    return ( $resources );
}

and here is what is returned:

<?

function seedme_services_create ( $data )
{
    $debug = fopen ( "/tmp/debug.txt", "a" );
    fwrite ( $debug, "entered seedme_services_create\n" );
    fwrite ( $debug, "data : " . print_r ( $data, TRUE ) . "\n" );

    // First check on required arguments
    if ( empty ( $data ) )
        return services_error ( 'Empty data set received!', 406 );
    if ( empty ( $data['email'] ) )
        return services_error ( 'Missing required email field!', 406 );
    if ( empty ( $data['api'] ) )
        return services_error ( 'Missing required API key field!', 406 );
    if ( empty ( $data['api'] ) )
        return services_error ( 'Missing required API key field!', 406 );

    $node = node_load ( 178 );
    fwrite ( $debug, "node : " . print_r ( $node, TRUE ) . "\n" );

    // Now create the new data set node
    /*
    $node = new stdClass();
    $node->type = 'user_data';
    $node->is_new = TRUE;
    node_save ( $node );
    return ( array ( "nid" => $node->nid ) );
    */
    return;
}
