Question

I am trying to create a custom web api skillset to connect to document intelligence directly. Created a skillset definition but it throws below error -

The request is invalid. Details: Cannot dynamically create an instance of type 'Microsoft.Azure.Search.DataIdentity'. Reason: Cannot create an abstract class.

Apologies for the delayed response. Just checking if it's working fine?

Based on my understanding of your issue, kindly check the sample:

If you're looking to implement authentication for your custom web API skill within a skillset, you might consider using the authResourceId property. This property is part of the skillset definition that enables Azure AI Search to authenticate to your custom web API using Managed Identity.

{
  "@odata.type": "#Microsoft.Skills.Custom.WebApiSkill",
  "description": "A custom skill that can identify positions of different phrases in the source text",
  "uri": "https://contoso.count-things.com",
  "batchSize": 4,
  "context": "/document",
  "inputs": [
    {
      "name": "text",
      "source": "/document/content"
    },
    {
      "name": "language",
      "source": "/document/languageCode"
    },
    {
      "name": "phraseList",
      "source": "/document/keyphrases"
    }
  ],
  "outputs": [
    {
      "name": "hitPositions"
    }
  ]
}

Just to highlight,

• Review your skillset definition and make sure it adheres to the expected structure.
• If you’re using any custom code or extensions, ensure they handle the correct class instantiation
