unable to start containers in cluster

[MNS26]

a few days ago i decides to switch to proxmox-nixos when i had to swap SSD's (dead main SSD)
i currently cant start containers and get
TASK ERROR: can't open '/nix/store/4x6sad43rd5c734q1afvvq4210b55fva-pve-container-5.2.6/share/lxc/config/common.seccomp' - No such file or directory
in the output window

i also noticed migrating containers causes a issue
the migration itself seems to go fine. but something after fails

Containers are not supported as of today, there is work towards that but not completed so far.

ah i see.
any insight on when a possible workaround is available?

i could also move some to the main node. but currently the containers are stuck in "migrating" state.
