Whisper API bad request error

I am using node js for open ai api. However, whenever I make an API call, I get this error:

Error: BadRequestError: {"message":"","type":"server_error","param":null,"code":null}

Here is my code for the API call:

    const type = await fileType.fromBuffer(audioFile);
    console.log(`Detected file type: ${JSON.stringify(type)}`);

    const response = await openai.audio.transcriptions.create({
        file: audioFile, // The audio file to transcribe.
        model: "whisper-1", // The model to use for transcription.
        response_format: 'json', // The format of the transcription.
        language: 'en' // Language

The file type of audioFile is m4a, which is supported when I checked the docs. Can someone please help me?

Hello, it looks like it is a server side error and not a code problem. If this problem continues you should contact support at help.openai.com
