I could not download recent video on nicovideo. Old one was no problem like this.

I tweeted at https://twitter.com/uaa/status/1273226483977207808 (see attached photo), JSON from old video returns "archive_h264_1600kbps_540p" contains bitrate. But new one returns "archive_h264_720p", no rate.

I think these difference made the problem. hope this help.
