Socket hang up while calling API from NodeJS #77
Description
I'm calling weasyprint-rest container from NodeJS application. But sometimes API call breaks with error Socket Hang up.
Here is Full error message,

[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.
