Rails deploy to heroku " Detecting rails configuration failed" and "/usr/bin/env: ‘ruby.exe\r’: No such file or directory"

Question

I'm getting a error message when deploying my rails application to heroku

I'm coding in a Windows laptop.

I get two distinct errors (I think they may be related).

First:

remote: /usr/bin/env: ‘ruby.exe\r’: No such file or directory

Then:

remote: Detecting rails configuration failed

I searched in Stackoverflow to see for solutions, I tried to apply:

windows heroku run rake db:migrate error "/usr/bin/env: ruby.exe: No such file or directory"

And it doesn't work.

Also I've tried to execute in my git bash:

dos2unix bin/bundle bin/rake bin/rails

What I have noticed is that it doesnt matter that I've changed ruby.exe to ruby (as said above), heroku still deploys looking for ruby.exe\r

This is the second time I deploy a Rails project in heroku, the first time I didnt have any problems, the second time I cloned the project and used it as template, with a different git repository.

Thanks!

UPDATE 2:

I can run it with no problems using heroku local so Im not sure whats causin the error.

EDIT 3

Well, I applied what is in these 2 answers: heroku /usr/bin/env: ‘ruby.exe\r’: No such file or directory problem https://help.github.com/en/articles/dealing-with-line-endings

Now the: 'remote: /usr/bin/env: ‘ruby.exe\r’: No such file or directory'

Doesn't appear anymore.

Still getting the rails configuration failed. These are the logs:

Well I fixed this by doing the following:

I setup the config:

heroku config:set AWS_ACCESS_KEY_ID=<something>
heroku config:set AWS_SECRET_ACCESS_KEY=<something>
heroku config:set AWS_REGION=<something>
heroku config:set S3_BUCKET_NAME=<something>

That didn't fully help but then again, I noticed that I was missing the master.key.

I also made sure that my config/enviroment/production.rb had:

config.require_master_key = true

So I added the config aswell:

heroku config:set RAILS_MASTER_KEY=<something>

After doing this, I did again the 'git push heroku master'

And it worked.
