🐛 Describe the bug

I'm using vllm v0.7.3 and openai 1.59.7.

I'm using openai stream mode with "logprobs" to True and "top_logprobs" to 5.
I observed following log is flushing in vllm log:

The following fields were present in the request but ignored: {'top_logprobs'}

This log disappears after I added top_logprobs field to DeltaMessage and ChatCompletionLogProb:

class DeltaMessage(OpenAIBaseModel):
    role: Optional[str] = None
    content: Optional[str] = None
    reasoning_content: Optional[str] = None
    tool_calls: List[DeltaToolCall] = Field(default_factory=list)
    top_logprobs: Optional[int] = 0   # this line.

class ChatCompletionLogProb(OpenAIBaseModel):
    token: str
    logprob: float = -9999.0
    bytes: Optional[List[int]] = None
    top_logprobs: Optional[int] = 0 # this line.
