I have installed this library in node js. I am trying to get an image from html but I get UnhandledPromiseRejectionWarning: Error: Browser is not downloaded. Run "npm install" or "yarn install" error always. OS: Ubuntu 18.04 LTS Node: v12.14.1 NPM: 6.14.5

Here is log:

@frinyvonnick I have the same issue

const nodeHtmlToImage = require('node-html-to-image');

export default async (req, res) => {
  try {
    const image = await nodeHtmlToImage({
      html: '<html><body><div><img src="https://domain.com/some_image.png" /><img src="https://domain.com/some_image.png" /></div></body></html>'
    });
    res.writeHead(200, { 'Content-Type': 'image/png' });
    res.end(image, 'binary');
    return res;
  } catch (e) {
    console.log(e);
    return res.status(400).json({ error: e });
  }
};

env: serverless function in next.js For now I'm testing this on local env
