react native ffmpeg-kit-react-native FFprobeKit how can i save return log? - ffmpeg

Question

I want to get the bitrate of the audio and store it in a variable. The output is normal, but I don't know how to save it.
static getAudio(
localFileName,
videoURI,
successCallback,
errorCallback,
) {
let outputPath = `${RNFS.CachesDirectoryPath}/${localFileName}.txt`; // 업로드된 파일을 캐싱하여 각 초마다 저장했을때의 path 를 등록
// const ffmpegCommand = `-ss 0 -i ${videoURI} -acodec copy -map 0:a:0 -vn -f rawvideo ${outputPath}`;
const ffmpegCommand = `-select_streams v -show_entries packet=size:stream=duration -of compact=p=0:nk=1 ${videoURI}` // 윈도우에서는 됨
//const ffmpegCommand = `ffprobe -v quiet -print_format json -show_format -show_streams ${videoURI}` // 윈도우에서는 됨
audio(ffmpegCommand, videoURI)
}
const audio = async (command, videoURI) => {
// FFprobeKit.executeAsync(command).then(async (session) => {
// FFprobeSessionCompleteCallback(session).then(function (res) {
// console.log(res)
// })
// })
try {
await FFprobeKit.executeAsync(
command,
).then(async information => {
console.log('들어옴')
const failStackTrace = await information.getFailStackTrace();
console.log(failStackTrace);
await information.getOutput().then(output => {
console.log(output)
});
});
} catch (error) {
console.log(error);
}
}
