Adding a new document in Couchdb ( iriscouch ) POST request fails with Status 500

A couple of months back,the code below worked perfectly and was used to add a new document in couchdb (iriscouch).

Now I'm getting a HTTP Status 500. Is there a workaround?

Code (in Node.js) :

var http=require('http');

var options = {
  host: 'sbose78.iriscouch.com',
  path: '/bosedb1',
  method: 'POST',

  headers:{
 'Content-Type':'application/json',
 'accept':'application/json'
   }
 };

var data={
   'servings' : 4,
   'subtitle' : "Delicious with fresh bread",
   'title' : "Fish Stew------"
};

var req = http.request(options, function(res) {
   console.log('STATUS: ' + res.statusCode);
   console.log('HEADERS: ' + JSON.stringify(res.headers));
     var body="";

   res.on('data', function (chunk) {
     body+=chunk;
         console.log('BODY(inside listener):\n ' + body);

   }); 

  console.log('BODY (outside listener): ' + body);

});


req.on('error', function(e) {
  console.log('problem with request: ' + e.message);
});



 //write data to request body
req.write(JSON.stringify(data));
req.end();

The response:

    STATUS: 500
HEADERS: {"content-type":"text/plain","content-length":"239"}
BODY(inside listener):
 Internal routing error
