Unrecognized request arguments supplied: azureSearchEndpoint, azureSearchIndexName, azureSearchKey, data_sources

Question

I'm having trouble making a request to the Azure OpenAI chat model, using my own data in Azure Blob Storage and the Search service as the search engine.

Last week, it was working just fine. I took the sample code available in the Azure OpenAI Studio portal and was able to use it in Postman and later in Power Automate. Here is proof of successful execution:

Here is the JSON used in Power Automate:

{
  "data_sources": [
    {
      "type": "azure_search",
      "parameters": {
        "endpoint": "https://mygptsearch.search.windows.net",
        "index_name": "azureblob-index",
        "semantic_configuration": "default",
        "query_type": "semantic",
        "fields_mapping": {},
        "in_scope": true,
        "role_information": "You are an AI assistant that helps people find information. Always search for knowledge in internal sources and return all links found in the following format: [Link Text](Link URL).",
        "filter": null,
        "strictness": 3,
        "top_n_documents": 1,
        "authentication": {
          "type": "api_key",
          "key": "mykey"
        }
      }
    }
  ],
  "messages": [
    {
      "role": "system",
      "content": "You are an AI assistant that helps people find information. Always search for knowledge in internal sources and return all links found in the following format: [Link Text](Link URL)."
    },
    {
      "role": "user",
      "content": "Ola, tudo bem?"
    }
  ],
  "temperature": 0,
  "top_p": 1,
  "max_tokens": 800,
  "stop": null,
  "stream": false,
  "past_messages": 10,
  "frequency_penalty": 0,
  "presence_penalty": 0,
  "azureSearchEndpoint": "https://mygptsearch.search.windows.net",
  "azureSearchKey": "
mykey
",
  "azureSearchIndexName": "azureblob-index"
}

Today, I was performing a test on the same implementation model, using the same JSON format provided by the playground, and it flagged the following parameters as unrecognized.

Full JSON used in Postman:

{
  "data_sources": [
    {
      "type": "azure_search",
      "parameters": {
        "endpoint": "https://dioazuresearch.search.windows.net",
        "index_name": "meuindice",
        "semantic_configuration": "default",
        "query_type": "semantic",
        "fields_mapping": {},
        "in_scope": true,
        "role_information": "Você é um assistente de IA que ajuda as pessoas a encontrar informações.",
        "filter": null,
        "strictness": 3,
        "top_n_documents": 5,
        "authentication": {
          "type": "api_key",
          "key": "mykey"
        },
        "key": "mykey",
        "indexName": "meuindex"
      }
    }
  ],
  "messages": [
    {
      "role": "system",
      "content": "Você é um assistente de IA que ajuda as pessoas a encontrar informações."
    },
    {
      "role": "user",
      "content": "Ola, tudo bem"
    }
  ],
  "temperature": 0.7,
  "top_p": 0.95,
  "max_tokens": 800,
  "stop": null,
  "stream": true,
  "frequency_penalty": 0,
  "past_messages": 10,
  "presence_penalty": 0,
  "azureSearchEndpoint": "https://dioazuresearch.search.windows.net",
  "azureSearchKey": "mykey",
  "azureSearchIndexName": "meuindice"
}

So basically, it doesn't recognize the parameters it told me to use. Can someone help me?
