downloader.getVideoInfo(request).data() return null data and response error：Transformation functions not found

[PeOS-China]

Hello, I used the response.data() method to get the youtube video information, but it returned nothing and I couldn't get the video playback URL or audio URL. And response error：Transformation functions not found
implementation 'com.github.sealedtx:java-youtube-downloader:3.2.8'

        var responseError: String? = null
        try {
            val request = RequestVideoInfo(videoId).clientType(ClientType.MWEB)
            val response: Response<VideoInfo> = downloader.getVideoInfo(request)
            responseError = response.error()?.localizedMessage
            val video: VideoInfo = response.data()
            val url = if(isVideo) {
                val videoFormats = video.videoFormats()
                if(videoFormats.isNotEmpty()) videoFormats.first().url()
                else ""
            } else {
                val audioFormats = video.audioFormats()
                if(audioFormats.isNotEmpty()) audioFormats.first().url()
                else ""
            }
            val details = video.details()
            val second = details.lengthSeconds()
            Log.d(tag, "JavaYT parse success（$videoId）($second): $url")
            return Triple(url, second, null)
        } catch (e: Throwable) {
            Log.d(tag, "JavaYT parse fail($videoId)：${e.localizedMessage}")
            Log.d(tag, "JavaYT parse fail($videoId) response error：${responseError}")
            return Triple("", 0, e)
        }
