Hi, can you post the lines above as well, so I can see which cmd triggered your error? Thanks.

Quickfix would be changing line 291
currentTime := data["currentTime"].(string)
to

currentTime := 0
if data["currentTime"] != nil {
    currentTime = data["currentTime"].(string)
}

Anyway I'll integrate more data checks soon, thanks for reporting this one :)

Will try that and revert.

Also I am noticing delay in music playback, after I select the video and the video starts playing on the Raspberry Pi. The delay is in the range 15 - 20 seconds. Is it normal?

Yea the script uses youtube-dl, which can take around 15 secs to start and fetch the video stream URL. Because there is no open API for obtaining the stream link from a video ID, we have to rely on youtube-dl here for now.

after Quickfix, the following build errors occurs:
