use the swagger-ui 2.2.10, It works fine. I found the https://github.com/swagger-api/swagger-ui/releases has a newer version 3.0.4, so I download the file and copy the dist file to Website Directory at /swagger-ui, It works and show the new Fresh UI.
We’re monitoring the latest version of swagger-ui and we’ll upgrade when it’s stabilized, we’ve found performance and stability issues with their new v3 upgrade which is why reverted back to the latest stable v2. Well check again before next release and will upgrade if their issues have been resolved.
