Server crashing when sending buffer reponse

[AndeYashwanth]

I am trying to send buffer data as response but the server is crashing when I do that. Below is the code to reproduce the issue.

app.get("/test", async(req, res) => {
    res.header("Content-Type", "application/octet-stream");
    console.log("test")
    const binaryData = new Uint8Array([0x01, 0x02, 0x03, 0x04]);
    const buffer = Buffer.from(binaryData);
    res.send(buffer);
})

Even using below code doesn't catch the error.

process
  .on('unhandledRejection', (reason, p) => {
    console.error(reason, 'Unhandled Rejection at Promise', p);
  })
  .on('uncaughtException', err => {
    console.error(err, 'Uncaught Exception thrown');
    process.exit(1);
  });

I noticed that the crash only happens when I run in docker container. It doesn't crash when running locally using ts-node src/index.ts. Below is my Dockerfile.

FROM node:22-alpine
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .

RUN npm run build

EXPOSE 3000

ENV NODE_OPTIONS="--enable-source-maps"

CMD ["node", "dist/index.js"]

There are no error messages or stack traces printed. Container just stops. As a workaround I'm converting it to base64 and sending json response.
