Deploying to a Rails app to Heroku via heroku-deploy.sh

Hello,

When I try deploying to Heroku via a heroku-deploy.sh i get:

./bin/heroku_deploy.sh $CIRCLE_SHA1 returned exit code 126
bash: line 1: ./bin/heroku_deploy.sh: Permission denied Action failed: ./bin/heroku_deploy.sh

Stack:
Ruby on Rails
Heroku

Previously I deployed successfully by specifying the app in circle.yml

Thanks
