Hello,
I'm having trouble with a previously working setup (not touched since autumn 24), When running the flake I now have the following error :

error: builder for '/nix/store/vx1l4rrh1f0z1asrv2iw5k1n19zxy307-python3.12-click-8.1.8.drv' failed with exit code 2;
       last 25 log lines:
[...]
 >   File "<frozen importlib._bootstrap>", line 1324, in _find_and_load_unlocked
       > ModuleNotFoundError: No module named 'flit_core'

Is it a known issue ?

Here is the line in the flake.nix

            app-server-poetry = mkPoetryApplication { projectDir = ./.; };
