Cannot push git repo to Heroku

Question

I try to push my git repo to Heroku, but I get error:


remote: -----> Installing node-v12.16.2-linux-x64
remote: -----> Detecting rake tasks
remote:

remote:  !     Could not detect rake tasks

 ! [remote rejected] master -> master (pre-receive hook declined)
error: не удалось отправить некоторые ссылки в «https://git.heroku.com/whispering-fortress-58873.git»

How to fix it? I've been trying to fix this for two days now.

Ruby version: 2.7.2
Rails version: 5.2.4.4
Gem version: 3.1.4
Bundler version: 2.2.7

Have you seen [this](https://stackoverflow.com/questions/65542961/rails-rake-issue-when-deploying-to-heroku?noredirect=1#comment115918974_65542961)? Maybe bundler version is not supported? — thiebo, Feb 03 '21 at 08:40

Checking error logs it seems that you need to push your branch to main

Try the following (or replace master with your current branch)

git push heroku master:main
