PROJECT_PATH is undefined

[619]

This is what I get when I follow the steps listed in the README.md

-----> Subdir buildpack app detected
PROJECT_PATH is undefined
! Push rejected, failed to compile Subdir buildpack app.
! Push failed

@619 try to use app instead projects/nodejs/app only value in PROJECT_PATH environment variable

[Diego-Paris]

I'm getting the same error mentioned but the solution provided by @mateussmohamed does not work for me. Is there another approach to this error? PROJECT_PATH continues to be undefined.

Hello, I'm having the same error as well. I have "Code" as the only value in my right-hand box on Config Vars and I am getting the same message in error as well:

"PROJECT_PATH is undefined
! Push rejected, failed to compile Subdir buildpack app."

I fixed this by just removing the build pack and in my travis.yml file added in a before_script: cd frontEnd
My travis file is in the parent folder of the project

I had the same problem, but I was able to fix it.
My github repository structure that I was hosting on Heroku was like this:

repository_name/
├─ my_project_to_run/
│   ├─ run.py
│   ├─ ...

I had set the PROJECT_PATH config var to repository_name/my_project_to_run but it didn't work.

Instead, inspired by @mateussmohamed reply,

@619 try to use app instead projects/nodejs/app only value in PROJECT_PATH environment variable

I set the PROJECT_PATH config var to only my_project_to_run and it worked flawlessly.

Hope it helps. 👍

Same Error!!!! Any Fix!?

Already defined the PROJECT_PATH in the setting tab and nothing.

this solution worked for me. Thanks, my time saver!

it did not work for me

Looks like if you have a single subdirectory, Heroku changes into it automatically and thus the build root is no longer your repository root. If that's the case, just add a subdirectory at root of your repo with a single empty file in it. E.g.

/my-project-dir/package.json
/empty-dir/.keep

You're right, I did what you suggested and worked for me! Thanks!

Thanks, it worked for me too

i had the same problem but i solved changing the path name from backend to Backend. It seems to be different to Heroku

[gosag15]

In case someone still has an issue with this. None of the above worked for me. My folder structure was mainfolder/subfolder/app and the project path was set to mainfolder/subfolder/ but it failed. I tried all the combinations above and they all failed... the final solution that worked for me was just ./

[jitDotBlake]

heroku is about to stop supporting builds on heroku-20, has anybody gotten it to work on a later stack?

[whusterj]

@jitDotBlake - Yes, this is working for me on heroku-24. It works by running a very simple bash script, so I expect it will continue working for a long time.

The error PROJECT_PATH is undefined is misleading. It can happen when the PROJECT_PATH variable is defined, but your directory is not found. In my case, I was working on a branch that had the directory, but I pushed main to heroku, which didn't have the directory, and so I ended up here.

Anyway, PR #13 improves the error messaging. IMO, it should be merged!
