Unsupported data type when making API request to Azure Open AI

I’m getting "unsupported data" error when trying to send post request to Azure OpenAI. What should I do to fix the error?

https://myopenai.openai.azure.com/openai/deployments/code-davinci-002/completions?api-version=2023-03-15-preview&API-KEY=xxxxxxxxxxxx&content-type=application/json

api-version = 2023-03-15-preview
API-KEY = xxxxx
content-type = application/json


{
     "model": "gpt-3.5-turbo",
     "messages": [{"role": "user", "content": "Say this is a test!"}],
     "temperature": 0.7
}

    Seems like you may be mixing davinci model in your deployment but gpt model in your body.

    I am experiencing a similar error when my model deployment is correct.
    Using gpt-35-turbo as an Azure deployment and api-key xxxx in header and api-version 2023-03-15-preview in url string.

    400 model_error
    Unsupported data type.

    Here is the payload.

    {
    "messages": [
        {
            "role": "system",
            "content": "You are an AI assistant that helps people find information."
        },
        {
            "role": "user",
            "content": "Why do some oranges have seeds and others do not?"
        }
    ]
}

    Try to use prompt with ChatML instead.

    For example:

    {
  "prompt": "<|im_start|>systemnAssistant is a large language model trained by OpenAI.n<|im_end|>n<|im_start|>usernWhat's the difference between garbanzo beans and chickpeas?n<|im_end|>n<|im_start|>assistantn",
  "temperature": 0.9,
  "top_p": 1,
  "frequency_penalty": 0,
  "presence_penalty": 0,
  "max_tokens": 256,
  "stop": ["<|im_end|>"]
}

    You are missing a chat/ in the URL. It shouldn’t be

    https://myopenai.openai.azure.com/openai/deployments/<deployment>/completions?api-version=2023-03-15-preview&API-KEY=xxxxxxxxxxxx&content-type=application/json

    but

    https://myopenai.openai.azure.com/openai/deployments/<deployment>/chat/completions?api-version=2023-03-15-preview&API-KEY=xxxxxxxxxxxx&content-type=application/json

    I was running into the same issue and it took me forever to figure out that the endpoint for the chat API is slightly different.
