I've run Liquidsoap 1.2.0 for a long time now on my old CentOS 6 server.
Now I am migrating to a new CentOS 7 system and I installed Liquidsoap
1.3.3 from radiorabe. But now liquidsoap fails to start and it outputs the
following error message...
At line 12, char 28:
this value has type
(default:_)->_ (*inferred at line 11*, char 19-115)
but it should be a subtype of
string
Here is the script code (*line 11* is highlighted in *bold*):

It's as if get_process_line has broken. The command line returns a string
just fine...
# curl --basic --user mark:python
http://localhost:3000/api/playlists/crimson/nextSong?format=text
/usr2/Blues/mp3-96kbps/Stack O Lee-Mark Jeghers-The Bluez Projekt-T4P
Music-2009.mp3
Can anyone help me troubleshoot this? Or might there be a better build I
should use? I am blocked from moving this over to my new server hardware
until I can figure this out!
Thanks much,
/Mark
