Hello everyone,

I’m trying to make an HTTP Node call in Copilot Studio and follow the structure outlined in this example. My current JSON body works fine in Power Automate Cloud Flow, but when I try to use the HTTP Node in Copilot Studio same payload is not working

Here’s the JSON structure that works in Power Automate using POST with POST https://<endpoint>.openai.azure.com/openai/deployments/<deploymentName>/extensions/chat/completions?api-version=2023-06-01-preview

{
  "messages": [
    {
      "role": "system",
      "content": "You are an AI assistant that helps people find information."
    },
    {
      "role": "user",
      "content": "@{triggerBody()?['text']}"
    }
  ],
  "temperature": 0,
  "top_p": 1,
  "frequency_penalty": 0,
  "presence_penalty": 0,
  "max_tokens": 800,
  "stop": null,
  "dataSources": [
    {
      "type": "AzureCognitiveSearch",
      "parameters": {
        "endpoint": "https://xxx.search.windows.net",
        "key": "xxxx",
        "indexName": "xxxx"
      }
    }
  ]
}

I'm trying to follow the syntax in Copilot Studio to use it in a HTTP node but same syntax and is returning "Error Message: HTTP request failed with status code 400 BadRequest. Error Code: HttpRequestFailure"
https://learn.microsoft.com/en-us/azure/ai-services/openai/reference#example-3

{
  messages: [
    {
      role: "system",
      content: "You are an AI assistant that helps people find information."
    },
    {
      role: "user",
      content: Topic.UserInput
    }
  ],
  temperature: 0,
  top_p: 1,
  frequency_penalty: 0,
  presence_penalty: 0,
  max_tokens: 800,
  stop: "null",
  dataSources: [
    {
      type: "AzureCognitiveSearch",
      parameters: {
        endpoint: "xxxx",
        key: "xxx",
        indexName: "xxx"
      }
    }
  ]
}

Any idea about how build this JSON in a HTTP Node in Copilot Studio?
