There are two cases where you might get that response:
- If bors thinks the pull request is closed.
- It has already been approved (either it’s in the queue or running).
If neither of these make any sense, you can check the dashboard to see what state bors thinks your pull request is in. If bors thinks it’s closed, but GitHub thinks it’s open, click the “Sync pull requests” button at the bottom of your repository’s page to fix it.
This piece of documentation was created in response to this forum’s search logs. Thanks, Discourse, for letting me know that people were interested in this!
