Unable to use Phi-3 vision in Azure AI Studio

I am following this tutorial.

I created an instance of phi-3-vision-128K-instruct. Once created, I went to the playground to test it.

I am sending the following request. When I click Test, I don't see any response. What I am doing wrong?

JSON (after Matthijs note, but I am still not getting response)

{
  "input_data": {
    "input_string": [
      {
        "role": "user",
        "content": "how can you help me"
      }
    ],
    "parameters": {
      "temperature": 0.7,
      "top_p": 0.9,
      "max_new_tokens": 1024
    }
  }
}

Please upload the JSON you're sending instead of a screenshot. Also your screenshot doesn't show the complete JSON. You have a typo in your JSON. It's temperature instead of temperator. I just tested with this JSON and it works:

{
  "input_data": {
    "input_string": [
      {
        "role": "user",
        "content": "how can you help me"
      }
    ],
    "parameters": {
      "temperature": 0.7,
      "top_p": 0.9,
      "max_new_tokens": 1024
    }
  }
}
