how to use functions feature within continuous conversation

[For-December]

Thank you for developing this powerful lib!
It always works well, but when I try to use functions feature, I' m in trouble.
I want to fulfill a continuous conversation with functions feature, for instance:

• ask chatGPT what' s the time
• chatGPT call my function to get current time
• then chatGPT reply to me with the time that my function returns

Just like the example: https://openai.com/blog/function-calling-and-other-api-updates

Here is my test code:

  // build conversation and send to openAI
  conversation.add_function(get_current_time()).unwrap();
  let res = conversation
      .send_message_functions(ask)  // ask is "what' s the time now?"
      .await
      .unwrap()
      .message_choices;

about get_current_time:

/// get current time
///
/// * time - the time that user asks
#[gpt_function]
async fn get_current_time(time: String) -> Value {
    println!("AI uses param: {time}");
    return Ok(json!({
        "time":"10:30"
    }));
}

my function ( get_current_time ) was called successfully, but I could' t get a expected reply about current time.

message_functions' length is 1, content is empty str
called message().content also return empty str

history like this:

maybe need this?( I guess...)

and when I called send_message_functions again, error occur:

I tried again and again, but couldn't be able to solve it, hope to get help

Could you check if the issue still persists with version from the function-invocation-fix branch?

@Maxuss
I write a testing code just now, the issue still persists.
But I got a warning while running, do I use functions feature correctly?
Here are all about testing code:

• main logic

  // some config code for client......

   let mut conversation = client.new_conversation();
    conversation.add_function(get_current_time()).unwrap();

    let res = conversation
        .send_message_functions("Please tell the current time.")
        .await
        .unwrap()
        .message_choices;

    println!("{}", res.len());
    for ele in res {
        println!("ele is: {}", ele.message.content);
    }
    println!("\nhistory is:{:#?}", conversation.history);

• gpt_function

/// get current time
///
/// * time - the time that user asks
#[gpt_function]
async fn get_current_time(time: String) -> Result<Value> {
    println!("AI uses param: {time}");
    let result: serde_json::Value = serde_json::json!({
        "time":"10:30"
    });
    result
}
