"Navigation failed because browser has disconnected!" but Puppeteer is outdated (1.7.x instead of 2.0.0)

[hermanbanken]

When running this plugin I see the error

⠼  Building for production...
[prerender-spa-plugin] Unable to prerender all routes!

After inspecting the source I added an additional console.error(err); process.exit(1); right before

        PrerendererInstance.destroy()
        const msg = '[prerender-spa-plugin] Unable to prerender all routes!'

This shows me the error message is "Navigation failed because browser has disconnected!"

Full stacktrace

Googling that I don't get much, except that people are using Puppeteer 2.0 now.

So there are 2 individual issues:

1. outdated Puppeteer via several levels of node_module dependencies
2. error is swallowed

Extra information, puppeteer is installing Chromium r686378 atm:

> puppeteer@1.20.0 install /project/node_modules/puppeteer
> node install.js
