Azure Unable to load shared library - using nodejs

I am having this error on my page.

iisnode encountered an error when processing the request. HRESULT: 0x2 HTTP status: 500enter code here HTTP reason: Internal Server Error

You are receiving this HTTP 200 response because system.webServer/iienter code heresnode/@devErrorsEnabled configuration setting is 'true'.

In addition to the log of stdout and stderr of the node.exe process, consider using debugging and ETW traces to further diagnose the problem.

The last 64k of the output generated by the node.exe process to stdout and stderr is shown below:

node.js:201 throw e; // process.nextTick error, or 'error' event on first tick ^ Error: Unable to load shared library C:\DWASFiles\Sites\leagues\VirtualDirectory0\site\wwwroot\node_modules\node-sqlserver\lib\sqlserver.node at Object..node (module.js:472:11) at Module.load (module.js:348:31) at Function._load (module.js:308:12) at Module.require (module.js:354:17) at require (module.js:370:17) at Object.

and this is my code for server.js

var sql = require('node-sqlserver');
var conn_str = the value of ODBC in Connection Strings;
var http = require('http');
var port = process.env.port;
http.createServer(function(req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.write("start");
res.end("finish");
sql.query(conn_str, "SELECT * FROM GAME_PARTICIPANT", function(err, results) {
    if (err) {
        res.writeHead(500, {'Content-Type': 'text/plain'});
        res.write("Database Error: " + err)
        res.end("");
        return;
    }
    res.writeHead(200, {'Content-Type': 'text/plain'});
    for (var i = 0; i < results.length; i++) {
        res.write("ID: " + results[i].PlayerID + " GameID: " + results[i].GameID + " Team: " + results[i].Team + " Confirmed: " + results[i].Confirmed + " RoleID: " + results[i].RoleID);
    }
    res.end("; Done.");
});
}).listen(port);
