Hello, I'm trying to transcript a mp3 video from cloudflare R2 with Node.js but i am getting an error:

{
  message: "Invalid file format. Supported formats: ['m4a', 'mp3', 'webm', 'mp4', 'mpga', 'wav', 'mpeg']",
  type: 'invalid_request_error',
  param: null,
  code: null
}

This is what i am trying to do:

        const videoAudio = await r2.send(
            new GetObjectCommand({
                Bucket: env.CLOUDFLARE_BUCKET_NAME,
                Key: `${videoKey}.mp3`,
            }),
        );

        console.log("contentType: ", videoAudio.ContentType);
        console.log("ContentLength: ", videoAudio.ContentLength);
        console.log("videoKey: ", videoKey);

        const formData = new FormData();

        formData.append("file", videoAudio.Body, {
            contentType: videoAudio.ContentType,
            knownLength: videoAudio.ContentLength,
            filename: videoKey,
        });
        formData.append("model", model);

        try {
            const response = await axios.post(
                "https://api.openai.com/v1/audio/transcriptions",
                formData,
                {
                    headers: {
                        Authorization: `Bearer ${env.OPENAI_API_KEY}`,
                        ...formData.getHeaders(),
                    },
                },
            );

            return {
                response,
            };
        } catch (err) {
            if (err.response.data.error) {
                throw err.response.data.error;
            }

            throw new RequestToExternalAPIError();
        }

console logs:
