Vision API AnnotationUrls and AuthenticationKind not uploading COCO file

Question

Getting error message: "message": "AuthenticationKind is required for registering dataset using AnnotationFileUrls." when using Azure Vision AI API.

This is the curl command I'm using

curl.exe -v -X PUT "https://xxx-computer-vision.cognitiveservices.azure.com/computervision/datasets/xxx-dataset?api-version=2023-02-01-preview" -H "Content-Type: application/json" -H "Ocp-Apim-Subscription-Key: xxx" --data-ascii "
{
'annotationKind':'imageObjectDetection',
'annotationFileUris':['https://xxx.blob.core.windows.net/xxx/xxx/train.json'],
'authenticationKind': 'Key',
}"

when I change 'annotationFileUris' to 'annotationFileUrls' the command is successful. However, it does not upload the train.json file as the COCO file on the Vision AI dataset because annotationFileUris is empty (see picture).

Can anyone help solve this please? Thank you.

Issue: error message: "message": "AuthenticationKind is required for registering dataset using AnnotationFileUrls." when using Azure Vision AI API.

Solution: Worked once changed "authenticationKind" to "authentication".

{
  "annotationKind": "imageObjectDetection",
  "annotationFileUris": [
    "https://xxx.blob.core.windows.net/xxx/xxx/train.json"
  ],
  "authentication": {
    "kind": "sas",
    "sasToken": "your_blob_key"
  }
}

Answer 2

Hello Clodagh Lynch,

Can you help me try the following JSON as the request body?

{
  "annotationKind": "imageObjectDetection",
  "annotationFileUris": [
    "https://xxx.blob.core.windows.net/xxx/xxx/train.json"
  ],
  "authenticationKind": {
    "kind": "sas",
    "sasToken": "your_blob_key"
  }
}

Name	Type	Description
sasToken	string	Optional. The sas token to access container. Only needed when Kind = Sas.

For more detailed information, please refer to this document.

Best regards,
Charlie
