I created a trial access for the Computer Vision API. On successful addition of the API to my subscription account URL's were printed on the screen as endpoint. They are listed here -

https://westcentralus.api.cognitive.microsoft.com/vision

https://westcentralus.api.cognitive.microsoft.com/vision

https://westcentralus.api.cognitive.microsoft.com/vision

https://westcentralus.api.cognitive.microsoft.com/vision

https://westcentralus.api.cognitive.microsoft.com/vision

I do not know why there are so many of same text. But, if you notice there is already vision to the URL. I copied this entire text and set to the environment variable. In the code the environment variable is added with /vision/v3.0/read/analyze causing the 404.

So, be careful when you copy paste :D.

To avoid this silly copy and paste issue; the code in the page could change to not have the vision appended to the endpoint.
