Is there a way we can reject the Pull Request creation if certain conditions fail ?
I am developing a GitHub App in nodejs and probot and would like to reject the pull request creation when the developer clicks on the “Create pull request” button if the validation (like checking for the presence of some pattern in the body of pull request) fails for Pull Request body.
So, fundamentally the Pull Request should not be created in the first place(and user should be taken back to the PR creation page), if certain validation fails.
i.e. be on the same pull request creation page, if validation of pull request body(or just any other logic) fails.
