git push heroku master 因“HTTP 400 curl 22 请求的 URL 返回错误”而失败

Question

I'm trying to push rails application that shows just "hello, world.".
Then I met an error like below.
I would like to know how to solve this problem.

$git push heroku master
Enumerating objects: 88, done.
Counting objects: 100% (88/88), done.
Delta compression using up to 4 threads.
Compressing objects: 100% (73/73), done.
Writing objects: 100% (88/88), 22.29 KiB | 1.71 MiB/s, done.
Total 88 (delta 2), reused 0 (delta 0)
error: RPC failed; HTTP 400 curl 22 The requested URL returned error: 400 Bad Request
fatal: The remote end hung up unexpectedly
Everything up-to-date

My procedures are below.
1.create rails application like below.
rails new sample
2.fix routes and application_controller to show hello, world. 3.change Gemfile.
3-1.declare sqlite3 in development and test group gem 'sqlite3'
3-2.declare pg in production group gem 'pg', '0.20.0'
4.execute bundle install --without production
5.execute git add .
6.execute git commit -m "initial commit for heroku"
7.confirm if it works by rails s and access to localhost:3000
8.execute heroku login and enter id and password.
9.execute heroku keys:add and the SSH key is created by this operation.
10.execute heroku create
11.execute git push heroku master and then I got the error

Each programs' version is below.
* Rails 5.1.6
* heroku/7.14.1 win32-x64 node-v10.9.0

What is this error and how can I avoid this error?
Please tell me if you need more information.

Answer 1

导航到存储库后，运行以下命令将缓冲区增加到 500MB：

git config http.postBuffer 524288000

Answer 2

In case it helps anyone, I had this exact same error pushing to Azure. It turned out I'd filled my App Service storage quota. I deleted a bunch of big files and the problem was solved.

Answer 3

In my case, I had to both change the remote URL to use the git: protocol instead of https: , and I also had to create a public key.

To get the current URL:

git remote get-url heroku

Supposing your URL is something like https://git.heroku.com/your-repo-here.git , you should use this command to use the git: protocol:

git remote set-url heroku git@heroku.com:your-repo-here.git

Create public key:

heroku keys:add
