Error running my script after upgrade to Ubuntu 24.04.1

[srs4511351]

I was unable to find any other issue about this problem.

My .liq script no longer works when run on Ubuntu 24.04.1
It works on Debian Bullseye systems, with this package.
liquidsoap/stable,now 2.1.3-2 arm64

I installed the package
liquidsoap/noble,now 2.2.4-1 arm64 [installed]
Version Liquidsoap 2.2.4-1+dev

The error when I run my script:

At ./op25.liq, line 61, char 0-0:

The error says it was at line 61 in my script, but there are only 60 lines in the file.
Has there been a change in the script language?

Hi @srs4511351,
Could you share the script?

[srs4511351]

Here's my script.
I had to put it in an archive, as .liq is not supported.
op25.liq.tar.gz

I've created the issue for this problem: #4124.
I think it would not be fixed in the ubuntu:24.04, so you will have to either build it yourself from opam, use containers or use packages from release artifacts.
