unable to parse Procfile

Question

I am trying to deploy an Heroku app.

I must be doing something wrong with the Procfile. When I run foreman check I get this error.

ERROR: no processes defined

I get pretty much the same thing when deploying on Heroku

-----> Building runtime environment
-----> Discovering process types

 !     Push failed: cannot parse Procfile.

The Procfile looks like this

web: node app.js

What did I miss?

update I re-did all from the start, It works properly now. I think I might have issue with Unix line ending

Answer 1

Is your Procfile in the root of your project? Is it spelled with a capital P? Does it have unix line endings?

Yes it's in the root. it's correctly spelled, and git track the correct spelling. I think I will got with the unix line endings because I am on windows. – Sebi

Answer 2

Just encounter "Push failed: cannot parse Procfile." on Windows. I can conclude that It IS "Windows-file format" problem, NOT the context of file itself.

make sure to create a clean file, maybe use Notepad++ or other advanced editor to check the file type.

Thank you! I was going crazy trying to figure this out. I re-created the file in Notepad++ and that solved the issue! – Kajdan

Answer 3

save as a utf-8 character file, rather than what it is - a utf 16 character file. this is a confirmed fix.

this one was the one helping me, the other top comment didn''t explain what kind of file character should we used – Crosier

Answer 4

Open your current Procfile with notepad. Create a new Procfile.txt and paste the content of your original Procfile . Save your Procfile and replace it with your new Procfile

This fixed it for me on Windows 10 PowerShell – Jillianjillie

Answer 5

I had the same issue, using VSCode I changed file to UTF-8 (bottom right), saved file and pushed it - and it was successful.

Answer 6

It is happening due to a different encoding type in your Procfile.

1. Open your Procfile in a text editor, preferably, Notepad.
2. Save the file and in the encoding option, change the encoding to UTF-8 (default is UTF-16).
3. Replace your current Procfile with this file in the root folder of your project and remove the .txt extension.

Push your code again and you'll be good to go!
