Socket hang up while calling API from NodeJS #77

I'm calling weasyprint-rest container from NodeJS application. But sometimes API call breaks with error Socket Hang up.

Here is Full error message,

Error: socket hang up
     at connResetException (node:internal/errors70414)
     at Socket.socketOnEnd (node_http_client505:23)
     at Socket.emit (nodeevents525:35)

     at processTicksAndRejections (node:internal/process/task_queues8321)
[Sep-29-2022 094346] [error]: Error: Error: socket hang up

Here is the code I'm using to call weasyprint-rest container,

const axios = require('axios')
const FormData = require('form-data')
const data = new FormData();

const html = `<html>....</html>`;
const images = [ "logo.png", "sign.svg"]
data.append("html", html);
images.forEach( image => data.append('asset[]', fs.createReadStream(path.join(baseDir, `/public/templates/images/${image}`))))

const configConvert = {
	url: process.env.WEASYPRINT_URL,
	headers: { ...data.getHeaders(), 'Connection': 'keep-alive' },
	responseType: "arraybuffer",
	method: "POST",
	data: data
};
    
const pdfResult = await axios(configConvert);
const base64data = new Buffer.from(pdfResult?.data, 'binary');

Any thought on how to fix it? Or any example to call it with library other than axios? Thank you.
