uv pip compile requires --universal flag

[M1kep]

Describe the bug
uv pip compile appears to require the --universal flag to complete.

To Reproduce
config.ini

[DEFAULT]
enable_tracking = False

Dockerfile

# Use a Python image with uv pre-installed
FROM ghcr.io/astral-sh/uv:python3.12-bookworm-slim

# Install the project into `/app`
WORKDIR /app

# Enable bytecode compilation
ENV UV_COMPILE_BYTECODE=1

# Copy from the cache instead of linking since it's a mounted volume
ENV UV_LINK_MODE=copy

RUN apt update
RUN apt install -y git

RUN uv pip install --system comfy-cli

COPY config.ini /root/.config/comfy-cli/config.ini

RUN --mount=type=cache,target=/root/.cache/uv \
    comfy --skip-prompt --here install --nvidia --fast-deps

COPY ./extra_model_paths.yaml /root/.comfy/extra_model_paths.yaml

## Reset the entrypoint, don't invoke `uv`
ENTRYPOINT []
CMD ["comfy", "launch", "--", "--listen", "0.0.0.0"]

Run: docker build --progress plain .

Output

Nice to have

Additional context
Adding "--universal" to the command resolved this issue for me:
