Hey Raffaele!

We test regressions around here as much as we can to ensure they don't repeat. Would you mind modifying an existing fixture (https://github.com/cloudfoundry/python-buildpack/tree/master/cf_spec/fixtures/flask_web_app for example) or providing us with one (as simple as possible) that demonstrates the issue and that this change fixes it?

We don't actually maintain most of the buildpack code, opting to depend on Heroku's excellent work in this area. However when a real problem and fix is available, we do all we can to ensure it's pulled in and tested, then we can push it upstream to heroku as well. With a fixture in place, we can then ensure the Heroku code does not regress.

Thanks for your time!

Hi @sandrinr -- it looks like someone has beaten us all to the punch and submitted a PR to Heroku to fix this typo. Thanks again for submitting your PR. I'm going to close it now in anticipation of Heroku picking up the fix at their end.

Perfect!
