Heroku throws an error like "Push rejected, Unauthorized access." [closed]

Question

I'm using GitHub for code commits, and that Git URL integrate to Heroku for deployment. I have done it many times, and every time it works, but now this time I got an error:

Push rejected, Unauthorized access

I'm using Node.js. as the back-end. Here is my package.json file (email replaced):

{
 "name": "wrapperdemo",
 "version": "1.0.0",
 "description": "Payment Gatway demo",
 "scripts": {
 "start": "node app.js"
},
"dependencies": {
"express": "~4.13.3",
"node-libcurl": "*",
"node-jquery-param": "*",
"xml2js": "^0.4.17"
},

}
