Missing URI for M3U entry

I receive an error message when trying to tune some stations. What does missing URI for M3U entry mean?

It's missing the url part, which would be https://5a5f765a4fcc2.streamlock.net:1936/live/nh4.stream/playlist.m3u8
in the example below.

#EXTM3U
#EXTINF:-1 channel-id="JPCAM" channel-number="20001" tvg-logo="https://github.com/fancybits/custom-channels-examples/raw/main/webcams/beach-logo.png" tvg-name="JPCAM" tvc-guide-title="Jennette's Pier" tvc-guide-description="Live beach cam at Jennette's Pier" tvc-guide-art="https://github.com/fancybits/custom-channels-examples/raw/main/webcams/beach-guide.png" tvc-guide-stationid="0",JPCAM
https://5a5f765a4fcc2.streamlock.net:1936/live/nh4.stream/playlist.m3u8
