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}
    at APIError.generate (/mnt/2tbdir/VSCodeProjects/sovarapp/backend/node_modules/openai/error.js:46:14)

  },
  error: { message: '', type: 'server_error', param: null, code: null },

  param: null,
  type: 'server_error'
}

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

I am also facing the same problem… can anyone please explain this issue.
