Flatpak missing version attribute in output

I want to automate some Flatpak-related things, and my current problem is listing all remote packages and their versions. For reproducibility, I am testing in a Docker container (fedora, debian or ubuntu) and doing:

# dnf install -y flatpak  # or apt
# flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo 

Now I can list the applications, but they don't have versions!

# flatpak remote-ls --columns=application,version | head -n 3
app.authpass.AuthPass
app.bbsync.BlackboardSync
app.bluebubbles.BlueBubbles

There is no version in an individual application details either:

# flatpak remote-info flathub org.gnome.Shotwell

_However_, if I do a search:

# flatpak search shotwell
Name            Description                   Application ID           Version       Branch       Remotes
Shotwell        Digital photo organizer       org.gnome.Shotwell       0.32.9        stable       flathub

I can suddenly see versions of all packages!

# flatpak remote-ls --columns=application,version | head -n 3
app.authpass.AuthPass	1.9.6_1904
app.bbsync.BlackboardSync	0.18.0
app.bluebubbles.BlueBubbles	1.15.0.0

Metadata (flatpak --version; source /etc/os-release && echo $PRETTY_NAME):

Flatpak 1.16.0
Fedora Linux 41 (Container Image)

Flatpak 1.14.6
Ubuntu 24.04.1 LTS

Flatpak 1.14.10
Debian GNU/Linux 12 (bookworm)

I am aware that using Flatpak in containers is not very useful, but my tests use containers and I don't want to have different behavior there. * How do I initialize Flatpak's remote information so it starts giving out version information on remote-ls? * Why do I only have this problem in containers, and not on my Fedora workstation?
