Should stdin always needed?

Describe the bug
I build a docker image for myself and everything seems nice. But when i run docker run -d valuecell:0.1.20, here comes the problem:

INFO:     Application startup complete.
INFO:     Uvicorn running on http://0.0.0.0:8000 (Press CTRL+C to quit)
ERROR:    Traceback (most recent call last):

Data adapters configuration completed

But, if run with docker run --it valuecell:0.1.20, works well.
Looks like the program listen STDIN for exit signal???

To Reproduce
The dockerfile which most comes from the official docker/DockerFile with only last CMD line changed:

FROM ghcr.io/astral-sh/uv:python3.12-bookworm-slim

# Install uv.
COPY --from=ghcr.io/astral-sh/uv:latest /uv /bin/uv

WORKDIR /app

# Pre-cache the application dependencies.
RUN --mount=type=cache,target=/root/.cache/uv \
    --mount=type=bind,source=uv.lock,target=uv.lock \
    --mount=type=bind,source=pyproject.toml /cxcvbnm,rtyuiop[],target=pyproject.toml \
    uv sync --locked --no-install-project

# Copy the application into the container.
COPY . /app

# Install the application dependencies.
RUN --mount=type=cache,target=/root/.cache/uv \
    uv sync --locked

EXPOSE 8000

# Run the application.
CMD ["uv", "run", "python", "-m", "valuecell.server.main"]

Steps to reproduce the behavior:

1. download offical release 0.1.20
2. unzip and cd valuecell-0.1.20/python
3. create the dockerfile in current dir
4. build image by docker build -t valuecell:0.1.20 .
5. just run docker run -d valuecell:0.1.20

Actual behavior
ERROR and exit.
