Node.js service Timeout issues - node.js

Question

The Node.js API service hosted on AWS times out at intervals and crashes the server. When I checked Cloudwatch logs, I saw this error come up often.
npm ERR! path /app
npm ERR! command failed
npm ERR! signal SIGTERM
npm ERR! command sh -c -- npm run build && node dist/server.js
npm ERR! A complete log of this run can be found in:

Here's my docker file
#!/bin/sh
FROM node:16-bullseye-slim
RUN apt-get update; \
apt-get install -y python3; \
apt-get install -y python2 make; \
apt-get install -y g++; \

WORKDIR /app
COPY package*.json ./
RUN npm install
RUN npm ci --only=production
COPY . .
CMD ["npm", "run", "start:server"]
EXPOSE 3000
My package.json file start script
"start:server": "npm run build && node dist/server.js"
I'm using Node version: v16.13.2
Npm version: 8.19.0
Not sure the cause of this issue.
