so I have my backend locally right now and I have an EC2 instance that has the API there. Timeout happens around 2 minutes after some request, my guess is that server.timeout is set to 2 minutes but I don’t know how to change it in my code.

Code for the API:

const express = require('express');
const cors = require('cors');
const bodyParser = require('body-parser');

const app = express();
app.use(cors());
app.use(bodyParser.json({limit: '30mb'}))
app.use(bodyParser.urlencoded({ limit: '30mb', extended: true }));

app.post('/calculate', async (req, res) => {
    POST CODE HERE
});

app.listen(3000, () => {
    console.log(`App listening on port 3000`);
});

Here is how I’m sending a file/data: I have an array called batchRequests, which lets say at the moment will have 5 batch requests

batchRequests.push(fetch('ip/calculate', {
                    method: 'POST',
                    body: JSON.stringify({file}),
                    headers: { 'Content-Type': 'application/json','Access-Control-Allow-Headers': '*',
                'Access-Control-Allow-Origin': '*' },
                }));

after this I send all batched requests concurrently with Promise

const batchResponses = await Promise.all(batchRequests);
requests.push(...batchResponses);

The error I’m getting on EC2 node is:

BadRequestError: request aborted
    at IncomingMessage.onAborted (/home/ec2-user/project/node_modules/raw-body/index.js:245:10)

    at Socket.emit (node:events:531:35)
    at TCP.<anonymous> (node:net:338:12)

The erorr I’m getting locally is:

    Error.captureStackTrace(err, this);
          ^

      timeout: undefined,
      bytesWritten: 2300660,
      bytesRead: 277
    }
  }
}

packages, just in case:

"dependencies": {
    "body-parser": "^1.20.2",
    "cors": "^2.8.5",
    "express": "^4.19.2"
  }

Node version: v20.14.0

I tried putting: res.socket.setTimeout(0); at the first line of the api post call but it didn’t work.
