Docker root user issue while using Godot Docker Example

Hello there! I'm trying to create Rivet integration with my own Multiplayer Library. But after deployment, Rivet CLI seems to not allow for root user. I'm not exactly sure how to make the DockerFile work as docker newbie myself. Helps are appreciated! DockerFile (same one from the wiki):

FROM ghcr.io/rivet-gg/images/godot:4.2 AS builder
WORKDIR /app
COPY . .
RUN mkdir -p build/linux \
    && godot -v --export-release "Linux/X11" --headless ./build/linux/game.x86_64

FROM ubuntu:22.04
RUN apt update -y \
    && apt install -y expect-dev \
    && rm -rf /var/lib/apt/lists/*
COPY --from=builder /app/build/linux/ /app

# Unbuffer output so the logs get flushed
CMD ["sh", "-c", "unbuffer /app/game.x86_64 --verbose --headless -- --server | cat"]

FROM ghcr.io/rivet-gg/images/godot:4.2 AS builder
WORKDIR /app
COPY . .
RUN mkdir -p build/linux \
    && godot -v --export-release "Linux/X11" --headless ./build/linux/game.x86_64

FROM ubuntu:22.04
RUN apt update -y \
    && apt install -y expect-dev \
    && rm -rf /var/lib/apt/lists/*
COPY --from=builder /app/build/linux/ /app

# Unbuffer output so the logs get flushed
CMD ["sh", "-c", "unbuffer /app/game.x86_64 --verbose --headless -- --server | cat"]

Hey! Checking this out now 🙂 So Rivet doesn't start uploaded containers that use root for security issues. So let's get this sorted for you Oh ya, this is totally my bad, I didn't add the change to make the Docker container non-root One sec

If you take a look at this repo, the example here should be pretty reliable 🙂 https://github.com/rivet-gg/examples/tree/main/godot/bomber
