Vision.ClientException when running for the first time

See original GitHub issue

Hi,

when running for the first time after creating the services on Azure, I get the following exception. Since it does not really say much, could you help me troubleshoot it?

Unfortunately, the ClientException thrown by the Vision API doesn’t indicate what the error is. This failure is occurring sending the test image through the pipeline, so the problem is most likely with either the API key being used or the endpoint. As Emmanuel pointed out the API will default to the westus region endpoint.

I’ll update the code so that this is in the configuration if you want to change it. In the meantime you can change this by changing line 23 of Microsoft.Cognitive.Skills\Vision.cs from: visionClient = new VisionServiceClient(visionApiKey); to: visionClient = new VisionServiceClient(visionApiKey, “northeurope.api.cognitive.microsoft.com”); where “northeurope.api.cognitive.microsoft.com” is the region you deployed the vision service to that are listed here: https://westus.dev.cognitive.microsoft.com/docs/services/56f91f2d778daf23d8ec6739/operations/56f91f2e778daf14a499e1fa

In Vision.cs line 23 the following modification helped me:

visionClient = new VisionServiceClient(visionApiKey, “https://westcentralus.api.cognitive.microsoft.com/vision/v1.0”);

Uri should be modified in line 142 as well:

var uri = “https://westcentralus.api.cognitive.microsoft.com/vision/v1.0/recognizeText?handwriting=true”;
