What the code does

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.
self.path = os.path.join(self.dir, constants.SETTINGS_FILENAME)
exec(compile(code, "<funplay_execute_python>", "exec"), namespace) # noqa: S102

Nothing serious here today
