        the bug you are facing.

        This must not include external libraries since we will run this in a

        Provide the bug's error. For example, `throw new Error('Something went
        wrong')` would have the error `Something went wrong`.

        **If the script does not throw**, write `no error` (case insensitive).

        How does the bug behave? Does it happen very rarely (flaky)? If there is
        a PDF problem, make sure the script writes the PDF somewhere in the
        current working directory.
