The WPF app raises a ClientException about cognitive-vision-windows

[chsienki]

HI @shajmerchant. The vision service was experiencing intermittent errors yesterday, but has now been resolved. Can you confirm if you still see the issue?

I found the same problem... and in the "Error" property inside the Exception, I can see the message: "Access denied due to invalid subscription key. Make sure to provide a valid key for an active subscription."

I just created the Key for "Computer Vision API" and it is valid for 30 days.

UPDATE
The KEY created thru microsoft.com/cognitive never worked (using my personal Microsoft Account)... BUT the KEY created thru the Azure Portal (using my company account) WORKED!

[chsienki]

Could you try changing the endpoint to https://westcentralus.api.cognitive.microsoft.com/vision/v1.0 and see if the microsoft.com/cognitive keys are working?

You can change the endpoint by passing it to the VisionServiceClient when it is created. For example on the analyze page it can be changed here: https://github.com/Microsoft/Cognitive-Vision-Windows/blob/master/Sample-WPF/AnalyzePage.xaml.cs#L76

[daveh551]

I have tried the C# Getting started sample, which DOES use that endpoint, and subscription key still fails.:

client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", "<mykey>");

            // Request parameters and URI
            string requestParameters = "language=unk&detectOrientation =true";
            string uri = "https://westus.api.cognitive.microsoft.com/vision/v1.0/ocr?" + requestParameters;

Returns response code 401 with message "Access denied"

[chsienki]

That's using westus can you try with https://westcentralus.api.cognitive.microsoft.com/vision/v1.0 ?

[daveh551]

Sorry, I missed that distinction!

Yes, I changed it to westcentralus and it worked. Thanks for your assistance.

Closing for now. If you're are still seeing Microsoft.ProjectOxford.Vision.ClientException, please include the content of that exception in your issue report. Thanks
