rtmp disconnect, no DASH data is available

As soon as I connect to the server log looks like this:

2018-7-18 01:15:01 5092 [INFO] [rtmp connect] id=IDQQI19K ip=::ffff:127.0.0.1 app=live args={"app":"live","type":"nonprivate","flashVer":"FMLE/3.0 (compatible; FMSc/1.0)","swfUrl":"rtmp://localhost/live","tcUrl":"rtmp://localhost/live"}

So both of DASH and HLS become unavailable within 5 seconds after rtmp connect. Here’s my file

const {NodeMediaServer} = require('node-media-server');

const config = {
    rtmp: {
        port: 1935,
        chunk_size: 60000,
        gop_cache: true,
        ping: 60,
        ping_timeout: 30
    },
    http: {
        port: 8000,
        allow_origin: '*',
        mediaroot: './media',
    },
    trans: {
        ffmpeg: 'C:\\Program Files\\ImageMagick-7.0.5-Q16\\ffmpeg.exe',
        tasks: [
            {
                app: 'live',
                ac: 'aac',
                // mp4: true,
                // mp4Flags: '[movflags=faststart]',
                hls: true,
                hlsFlags: '[hls_time=2:hls_list_size=3:hls_flags=delete_segments]',
                dash: true,
                dashFlags: '[f=dash:window_size=3:extra_window_size=5]'
            },
        ],
    },
};

const nms = new NodeMediaServer(config); //todo: cluster
nms.run();
