Vision API asks for AuthenticationKind while creating a training data set

Question

I am following this article
https://learn.microsoft.com/en-us/azure/ai-services/computer-vision/how-to/model-customization?tabs=rest

As a first step, I am required to make a PUT call curl.exe -v -X PUT "https://<endpoint>/computervision/datasets/<dataset-name>?api-version=2023-02-01-preview" -H "Content-Type: application/json" -H "Ocp-Apim-Subscription-Key: <subscription-key>" --data-ascii " { 'annotationKind':'imageClassification', 'annotationFileUris':['<URI>'] }" When I do make this call by pointing the annotationFileUri to my coco file in blob storage. I end up getting this error.

{"error":{"code":"InvalidRequest","message":"AuthenticationKind is required for registering dataset using AnnotationFileUrls."}}

I tried adding this in the request body - however I still get the same error

"authenticationKind": "AzureBlob",

Hi @vishal Prabhu ,

Thank you for using Microsoft Q&A forum.

I tried to repro from my end using POSTMAN tool and was successfully able to create a new dataset in the Azure vision studio. Please find below:

Then checked the Azure AI Vision studio.

Kindly ensure that the correct parameters are used. See below:

"annotationFileUrls" instead of "annotationFileUris"

"authenticationKind" instead of "AuthenticationKind"

{
  "annotationKind": "imageClassification",
  "annotationFileUrls": ["YOUR_annotationFileUrl"],
  "authenticationKind": "Key"
}

Hope this helps. Do let us know if you any further queries.
