CDN for Custom Vision JavaScript APIs
I'm trying to create an Azure Custom Vision Training API client in a browser (not Node.js). I would like to know if there is a CDN that hosts the API. The documentation here seems to assume that I have the JavaScript libraries downloaded to my host. I tried to consume them from jsdelivr.net but it appears to be giving me the wrong version, based on this error message I get when trying to make a call.
Error: Access denied due to invalid subscription key or wrong API endpoint. Make sure to provide a valid key for an active subscription and use a correct regional API endpoint for your resource.
I have checked and rechecked the key, and tried both of my keys, so I do not believe that is the issue.
