I’m trying to query AzureOpenAI for chat completions, with on my own data (Azure Search), from TypeScript code.
I use packages @azure/[email protected] and [email protected].

I followed the instructions from https://github.com/Azure/azure-sdk-for-js/blob/main/sdk/openai/openai/MIGRATION.md#azure-on-your-data

import "@azure/openai/types"; is properly declared:

The code is as in the documentation:

const response = await client.chat.completions.create({
  model: '',
  messages,
  data_sources: [
    {
      type: "azure_search",
      parameters: {
        endpoint: "XXXX",
        index_name: "YYYY",
        authentication: {
          type: "system_assigned_managed_identity",
        },
      },
    },
  ]
});

End yet, parameter data_sourceis not recognized.
The error reads: Object literal may only specify known properties, and 'data_sources' does not exist in type 'ChatCompletionCreateParamsBase'

What am I missing here?

I uninstalled and re-installed both packages openai and @azure/openai, I tried different sets of parameters on client.chat.completions.create.
Also, I cannot find any reference to parameter data_sources in the node_modules folder of my project.
