Gpt-4o-audio-preview api error

I am making a voice chatbot with react native.
So at first, I converted the voice recording file to text using whisper-1 and sent it to gpt-4o, but it took too long.
So I want to send the voice recording file to gpt-4o-audio-preview and get the response as text or voice.
Below is the code I wrote.
‘transcribeAudio’ works fine, but ‘sendAudioToGPT’ gives an error. Please help me.
For reference, the voice recording file is in .m4a format.


  const transcribeAudio = async (uri: string) => {
    try {
      const response = await FileSystem.uploadAsync(
        "https://api.openai.com/v1/audio/transcriptions",
        uri,
        {
          headers: {
            Authorization: `Bearer ${API_KEY}`,
            "Content-Type": "multipart/form-data",
          },
          httpMethod: "POST",
          uploadType: FileSystem.FileSystemUploadType.MULTIPART,
          fieldName: "file",
          mimeType: "audio/mpeg",
          parameters: {
            model: "whisper-1",
          },
        }
      );

      const parsedResponse = JSON.parse(response.body);
      const transcribedText = parsedResponse.text;

      const botMessage = {
        role: "bot",
        content: transcribedText || "fail",
      };

      setMessages((prevMessages) => [...prevMessages, botMessage]);
    } catch (error) {
      console.error("Whisper API Error:", error);
    }
  };

  const sendAudioToGPT = async (uri: string) => {
    try {
      const response = await FileSystem.uploadAsync(
        "https://api.openai.com/v1/chat/completions",
        uri,
        {
          headers: {
            Authorization: `Bearer ${API_KEY}`,
            "Content-Type": "multipart/form-data",
          },
          httpMethod: "POST",
          uploadType: FileSystem.FileSystemUploadType.MULTIPART,
          fieldName: "file",
          mimeType: "audio/mpeg",
          parameters: {
            model: "gpt-4o-audio-preview",
          },
        }
      );

      await console.log(response);
    } catch (err) {
      setError("fail");
      console.error("API error:", err);
    } finally {
      setLoading(false);
    }
  };```
