Railpack - New build issue.

I have something weird.

Railpack builds fails because it can't find and copy /app/nickpacks.toml. Which sounds weird because why would I need nickpacks.toml to build with railpack …

Unfortunately the build logs of the last successful build (currently deployed) disappeared (why in the world are they deleted ?).
But I suspect an update to RAILPACK that break my build.

╭────────────────╮
│ Railpack 0.8.0 │

↳ Using config file `railpack.json`
⚠ The config file format is not yet finalized and subject to change.
↳ Found .dockerignore file, applying filters
↳ Using provider Python from config

Packages

pipx     │  1.8.0   │  railpack default (latest)
pipx:uv  │  0.8.22  │  railpack default (latest)

Successfully prepared Railpack plan for build

copy .python-version

install mise packages: pipx, pipx:uv, python
mise pipx:uv@0.8.22 ✓ installed

pipx install uv

copy /mise/shims, /mise/installs, /usr/local/bin/mise, /etc/mise/config.toml, /root/.local/state/mise, /app/.python-version, pyproject.toml, uv.lock

uv sync --extra production --frozen

copy / /app, /pyproject.toml /app/pyproject.toml, /nickpacks.toml /app/nickpacks.toml
ERROR: failed to build: failed to solve: lstat /nickpacks.toml: no such file or directory

So very obviously there's now a COPY of /nickpacks.toml /app/nickpacks.toml which should not be here…
