Netlify get TimeoutError if the page has animations

[Luca]

If the page subscribed to animationFrame, Netlify goes in timeout.

The workaround is not to generate static pages specifing urls = []:

conf : Starter.ConfMain.Conf
conf =
    { urls = []
    , assetsToCache = []
    }

I tried adding args: ['--headless'] as suggested in some post:

const browser = await puppeteer.launch( conf.headless ? { headless: true, args: ['--headless'] } : { headless: false } );

This solve the issue in my local machine but not on Netlify. Need more investigation.

This is the complete error:
