I'm getting this error 'No matching user found' while sending generic messages in this context only

I am getting an error on the node.js console when sending a generic message.I'm able to send regular text message but I'm having a problem with generic message..

   { error: 
  { message: '(#100) No matching user found',
    type: 'OAuthException',
    code: 100,
    fbtrace_id: 'BLguK1o+VsH' } } } 

function which sends the generic message.

function sendGenericMessage(recipientId, news) {
var messageData = {
    recipient: {
        id: recipientId
    },
    message: {
        attachment: {
            type: "template",
            payload: {
                template_type: "generic",
                elements: []
            }
        }
    }

}

for (var counter = 0; counter < 2; counter++) {
    messageData.message.attachment.payload.elements.push({
        title: news.articles[counter].title,
        subtitle: news.articles[counter].description,
        item_url: news.articles[counter].url,
        image_url: news.articles[counter].urlToImage,
        buttons: [{
            type: "web_url",
            url: news.articles[counter].url,
            title: "Open Web URL"
        }, {
            type: "postback",
            title: "Call Postback",
            payload: "Payload for " + (counter + 1) + "bubble",
        }],
    });
};

console.log("Generic message ==== " + messageData)

callSendAPI(messageData);}

API call function:

function getTopNews(recipientId){

var form = {};
var url = 'https://newsapi.org/v1/articles?source=the-times-of-india&sortBy=top&apiKey=*****'

request.get({url: url, form: form, headers: ''}, recipientId, function (e, r, b) {
    //callback body
    if (! e && r.statusCode == 200){
        var body = JSON.parse(b);
        console.log(body);
        console.log("----CHECK-----"+ recipientId)
        sendGenericMessage(recipientId, body);
    }else{
        console.error("Unable to receive the news");
        console.error(r);
        console.error(e);
    }

})

}

When I try to send generic template example which was given in facebook documentation this wont happen.

I tried hard coding all the values such as url, title and everything even though the error was recurring.
