git, Heroku: pre-receive hook declined
Make sure you are pushing a repo that contains a proper supported app ( Rails, Django etc.) and you are not just pushing some random repo to test it out.
Newbie in Heroku: Error when push my app to Heroku
If that is not the case and you are pushing what you think is a valid app, contact Heroku support and they will fix it for you.
remote rejected master - master (pre-receive hook declined)
Make sure that your Rails app is in the root of the repo, the Gemfile is present and properly named. It is basically not able to detect your code base as one of the supported project types and hence failing it. Also, even if you do have a proper project, make sure it is part of the repository and you have committed it fine (
git status will help you here and a
ls should help you verify the project structure).
Heroku deploy error - ! [remote rejected] master - master (pre-receive hook declined)
As found in this github issue it was an error with the git repo still thinking
client was a submodule. The fix is to remove the
client folder from git tracking and add it back as regular files:
git rm -f --cached client && git add . && git commit -m 'Add client folder back to git repo' && git push heroku master
! [remote rejected] master - master (pre-receive hook declined) when trying to deploy mern app to heroku
The error seems clear to give you the reply:
We have detected that you have triggered a build from source code with
version 377a2a25a1b56c226e11f9f9c45f371cc85adcea remote: ! at least
twice. One common cause of this behavior is attempting to deploy code
from a different branch.
That string is a hash of your bundle, the error is telling you that you already deployed the same bundle.
My guess is that you pushed the same bundle from the develop branch instead of the master before.
I suggest you make a change, create a new release and push from the master branch this time.
remote: ! If you are developing on a branch and deploying via git you must run:
remote: ! git push heroku <branchname>:main
tells you how to deploy from a different branch during development.
Git Heroku error [remote rejected] ... (pre-receive hook declined)
I found out what the problem was.
I think Heroku didn't support my encoding type, so it added some weird characters to my runtime.txt. But after a change to UTF-8 (I think, it was a long time ago) everything worked fine.
! [remote rejected] master - master (pre-receive hook declined) error: failed to push some refs to '...''
cd .. and then
git subtree push --prefix server heroku master. this way the problem was solved. For reference: https://dev.to/stlnick/how-to-deploy-a-full-stack-mern-app-with-heroku-netlify-ncb
