Проблема с heroku

Пытаюсь выставить приложение на сервер heroku,но не получается,делаю всё как по инструкции

Install the Heroku CLI Download and install the Heroku CLI.

If you haven't already, log in to your Heroku account and follow the prompts to create a new SSH public key.

$ heroku login

Create a new Git repository Initialize a git repository in a new or existing directory

$ cd my-project/
$ git init
$ heroku git:remote -a name

Deploy your application Commit your code to the repository and deploy it to Heroku using Git.

$ git add .
$ git commit -am "make it better"
$ git push heroku master

Existing Git repository For existing repositories, simply add the heroku remote

$ heroku git:remote -a name

После ввода команды

$ git push heroku master

Выходит ошибка

Красным подчеркнута только ошибка что ниже

! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/name.git'

Пытался делать pull перед push как советовал гугл,но это не особло помогло И если поможет,то на сайте https://git.heroku.com/name.git только надпись Method Not Allowed
