What version of Cloud Foundry and CF CLI are you using? (i.e. What is the output of running cf curl /v2/info && cf version?

$ cf version

What version of the buildpack you are using?

buildpack: https://github.com/cloudfoundry/php-buildpack.git

If you were attempting to accomplish a task, what was it you were attempting to do?

I’m attempting to pass options to composer but nothing worked. So with these .bp-config/options.js

{
  "WEB_SERVER": "httpd",
  "ADMIN_EMAIL": "[e-mail]",
  "COMPOSER_INSTALL_OPTIONS": [
    "--this-should-fail"
  ],
  "COMPOSER_VENDOR_DIR": "pbtest"
}

What did you expect to happen?

I expected cf push to fail with an invalid option as it does on the CLI:

composer --this-should-fail


  [Symfony\Component\Console\Exception\RuntimeException]
  The "--this-should-fail" option does not exist.

And I expected composer to vendor stuff into pbtest

What was the actual behavior?

• No failure
• SSH into container and find . -name 'pbtest' turns up nothing

Completed run, no errors.

Please confirm where necessary:

• I have included a log output
• My log includes an error message
• I have included steps for reproduction

I think I see the issue. You have .bp-config/options.js, but it should be .bp-config/options.json. Breaks as expected if I rename the file.
