libsoup3 was released in late 2021. This is a major API bump from libsoup2.4.

The Debian GNOME maintainers would like to stop building libsoup2.4.
Therefore, please stop using libsoup2.4.

It looks impractical for all affected packages to stop using
libsoup2.4 in time for Debian 13 "Trixie", but we intend to make these
bugs RC early in the Debian 14 "Forky" development cycle.

There is some documentation and many examples for porting away from
libsoup2.4 at
https://gitlab.gnome.org/GNOME/libsoup/-/issues/218

It appears like this has been done in an upstream merge request.
Please look into cherry-picking that fix for Debian.

Jeremy Bícha
