I have setup my CI to run tests an deploy to Heroku(only for master). The builds run successful when are run for master branch, but when are run for a PR they fail with following message:

My .circleci/config.yml is the following:

fingerprints:

- deploy:

command: |
if [ “${CIRCLE_BRANCH}” == “master” ]; then
git push heroku-dev master
