PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• If contributing template-only or documentation-only changes which will change sample output, build the project beforehand.
• Run the shell script ./bin/generate-samples.shto update all Petstore samples related to your fix. This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master. These must match the expectations made by your contribution. You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*. For Windows users, please run the script in Git BASH.
• File the PR against the correct branch: master
• Copy the technical committee to review the pull request if your PR is targeting a particular programming language.

You might want to do git commit --amend --no-edit && git push -f The circle CI build timed out for me as well and just needed to be rerun

Pushed 765c7bf to fix the CI failure. Let's see how that goes.

@codymikol FYI. Another way is to close and reopen the PR to trigger all the CI jobs.

[wing328]

I know how to fix the CI failures. Will do it later this week.

@stcarrez Not sure why but I couldn't fix the issue in your branch. I've created #7719 instead.

@wing328, thanks for the integration! I'm closing this pull request since you integrated it.
