Couldn’t find that process type, Heroku

This may happen if your procfile is misspelt, such as “procfile” or “ProcFile” etc. The file name should be “Procfile” (with a capital P).

sometimes changing the file name is not anough, because git wouldn’t spot the change. I had to delete the Procfile completely, then commit the change, than add it again with the right name, and then commit that again:

  1. remove your procfile
  2. git commit
  3. add a new procfile with the exact name “Procfile”
  4. commit again
  5. git push heroku master (or main – new heroku projects now uses main)

should work!
