I'm trying to deploy a server on my pro account but it keeps seeming to pick up that it has 20mb of memory instead of 32gb.

I've attached a copy of my dockerfile to show what it should be picking up

# --- Base Image ---

# Use a specific version of Node.js 20 LTS for reproducible builds.

FROM node:20.11.1-bullseye-slim as base

# --- Environment Variables ---

# Set essential ENV variables at the top for clarity.

# Tells Puppeteer to use the version of Chrome we install below, not download its own.

ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true

# Points Puppeteer to the installed Chrome executable.

ENV PUPPETEER_EXECUTABLE_PATH=/usr/bin/google-chrome-stable

# --- CRITICAL FIX 1: Correct Node.js Memory Settings ---

# REMOVED the hardcoded --max-old-space-size. This is the most important change.

# Now, Node.js will automatically detect the container's memory limit set in Railway.

# Note: Railway doesn't allow --expose-gc, so we leave NODE_OPTIONS empty or unset

# ENV NODE_OPTIONS=""

# --- CRITICAL FIX 2: Add Puppeteer flags for stability in containers ---

# These flags are essential for running Chrome headless in a Docker environment.

# They reduce memory usage and prevent crashes related to sandboxing and shared memory.

ENV PUPPETEER_ARGS="--no-sandbox --disable-setuid-sandbox --disable-dev-shm-usage --disable-accelerated-2d-canvas --disable-gpu --no-first-run --no-zygote --single-process --disable-background-networking"

# Set the working directory

WORKDIR /app

# --- System Dependencies ---

# Install Google Chrome and its dependencies cleanly.

# Using --no-install-recommends reduces the final image size.

RUN apt-get update \

&& apt-get install -y --no-install-recommends \

wget \

gnupg \

ca-certificates \

# These are the dependencies Puppeteer needs to run Chrome
