Why is my OpenAPI spec no longer working in GitBook?

Hi everyone! 👋

If you're seeing issues with your OpenAPI spec in GitBook, it may be due to recent improvements we’ve made to our spec validation process. These updates are meant to identify issues earlier, so your docs stay consistent and reliable for readers.

✅ What you can do:
Try pasting your spec into the editor.swagger.io to check for any formatting or structural issues.
If you're still having trouble after validating your spec, feel free to reach out to us at support@gitbook.com
