Opam install 2.3.0 build error but still installs

[periode]

Description

Hi!

I'm upgrading from 2.3.0-rc to 2.3.0 via opam install and it apparently succeeds but still throws this error:

[ERROR] The compilation of liquidsoap.2.3.0 failed at "dune build -p liquidsoap -j 7 --promote-install-files=false @install".

Even though liquidsoap --version afterwards outputs:

Liquidsoap 2.3.0+dev
Copyright (c) 2003-2024 Savonet team
Liquidsoap is open-source software, released under GNU General Public License.
See <http://liquidsoap.info> for more information.

So it installs but docs fail?

Steps to reproduce

opam update
opam upgrade
opam install liquidsoap.2.3.0

Expected behavior

No errors during build.

Liquidsoap version

Additional Info

Thanks!

FYI: installing 2.3.1 from source, and then unpinning all liquidsoap-* and then opam install, but I wonder if this will create problems in future releases
