Returns not found

[PilatP]

azuracas + liquidsoap
I have function to find a today news

def get_today_news() =
  try
    current_date = time.string("%d.%m.%Y")
    files = playlist.files("#{playlist_dir}/playlist_news.m3u")
    news =
      list.find(
        fun (metadata) -> string.contains(substring=current_date, metadata),
        files
      )
    meta = parse_annotate(news)
    track_file_name =
      string.replace(
        pattern=media_dir, (fun (_) -> ""), metadata.filename(meta)
      )
    log_data(
      tracks_log_file,
      "Today news: #{track_file_name} #{meta['duration']}s"
    )
    news
  catch err do
    print(
      "get_today_news #{err}"
    )
    null()
  end
end

After the script was run I uploaded a news track новости_06.05.2025.mp3 and I'm sure that the playlist was updated.

But I'm getting

get_today_news error(kind="not_found",message="no default value for list.find",positions="at /usr/share/liquidsoap/libs/thread.liq, line 64 char 4 - line 71 char 7, at /usr/share/liquidsoap/libs/thread.liq, line 67, char 6-9, at /var/azuracast/stations/red_radio/config/liquidsoap.liq, line 492, char 3-31, at /var/azuracast/stations/red_radio/config/liquidsoap.liq, line 439, char 9-25, at /var/azuracast/stations/red_radio/config/liquidsoap.liq, line 214 char 2 - line 237 char 5")

It's weird but is there any cache?

files = playlist.files("#{playlist_dir}/playlist_news.m3u")

If I restart liquidsoap it's going to find the news.

Hi @PilatP,
I recommend using log to print all necessary values.

    playlist_path="#{playlist_dir}/playlist_news.m3u"
    files = playlist.files(playlist_path)
    log.debug("playlist_path=#{playlist_path}, files=#{files}", label="get_today_news")
    news = list.find(
      fun (path) -> begin
        result = string.contains(substring=current_date, path)
        log.debug("path=#{path}, current_date=#{current_date}, result=#{result}", label="get_today_news")
        result
      end,
      files
    )

By the way, if I were you, I would use the ISO 8601 date format.

The playlist is created by AzuraCast

playlist_news = playlist(id="playlist_news",mime_type="audio/x-mpegurl",mode="normal",reload_mode="watch","/var/azuracast/stations/red_radio/playlists/playlist_news.m3u")
ignore(playlist_news)

The news were uploaded at May 14 16:50

ls -lh ../media/Новости/новости_15.05.2025.mp3
-rw-r--r-- 1 azuracast azuracast 2.8M May 14 16:50 ../media/Новости/новости_15.05.2025.mp3

The playlist playlist_news was not reloaded

ls -lh ../playlists/playlist_news.m3u 
-rw-r--r-- 1 azuracast azuracast 2.2K May 14 12:28 ../playlists/playlist_news.m3u

And there is no the news

cat ../playlists/playlist_news.m3u
annotate:title="Новости",artist="Красное радио ФРА",duration="331.00",song_id="448165cca541fd43888f3e06848a2dd0",media_id="2553",playlist_id="22":media:Новости/новости_06.05.2025.mp3

Whose responsibility is it to reload the playlist liquidsoap or azuracast? What should I do in that case?

Upd. It's wierd. The news is in the playlist

but the playlist_news.m3u is still empty.
I guess I miss something ).
