[Bug]: Errors with perplexity and anthropic calls with Tools

[simonljn]

What happened?

Reopening with python example.

I try to call different models with tool calls. Working on openai but not on some other ( sonar / claude )

Using : litellm 1.71.1

Is this planned to be supported ?

import openai

client = openai.OpenAI(api_key="TOKEN",base_url="LITELLM-SERVER")

response = client.chat.completions.create(model="PERPLEXITYMODEL", messages = [
      {
        "role": "assistant",
        "tool_calls": [
          {
            "function": {
              "arguments": '{"query":"foobar"}',
              "name": "Search",
            },
            "id": "call_ShUM9uxonziXPYjU9a4uoy4s",
            "type": "function",
          },
        ],
      },
      {
        "content": "this is a tool response",
        "role": "tool",
        "tool_call_id": "call_ShUM9uxonziXPYjU9a4uoy4s",
      },
      {
        "content": "hi",
        "role": "user",
      },
    ])

'litellm.BadRequestError: PerplexityException - ["At body -> messages -> 0 -> content: Field required", "At body -> messages -> 1 -> role: Input should be 'system', 'user' or 'assistant'"].
