Error 5: this value has type unit

At /etc/liquidsoap/simple.liq, line 7, char 13-22:
myplaylist = playlist("/media/songs")

Error 5: this value has type
  unit
but it should be a subtype of
  (_) -> _

simple.liq:

#!/usr/bin/liquidsoap

# Log dir
# log.file.path.set("/tmp/radio.log")

# Music
myplaylist = playlist("/media/songs")

# Some jingles
jingles = playlist("/media/jingles")

# If something goes wrong, we'll play this
security = single("/media/jingles/050723 RADIO SOM DO MATO VINHETA 001.mp3")

# Start building the feed with music
radio = myplaylist

# Now add some jingles
radio = random(weights = [1, 4],[jingles, radio])

# And finally the security
radio = fallback(track_sensitive = false, [radio, security])

# Stream it out
output.icecast(%vorbis,
  host = "localhost", port = 8000,

  radio)

Why liquidsoap can't read directories anymore?

Hi @sistematico,
The original script should work fine. I need additional info about your installation, probably something is wrong with the standard library.

1. How did you install liquidsoap?
2. Could you upload the result of liquidsoap --build-config?
3. What happens when you run liquidsoap --interactive?
   Then type playlist("/media/songs");; and hit enter.

Nevermind, I downloaded it again and tested it, now it seems that everything works normally, I'm sorry for the false positive, and I really appreciate your attention!
