Puppeteer not retrieving assets on GAE while working locally

Using puppeteer on GAE causes resource-heavy pages (like Shopify) to miss images and icons, while local runs behave well. GAE never requests these assets; what might be wrong?

i’ve seen similar issues - might be gae security blocking some asset calls. try tweaking puppeteer flags to mimic a normal browser request. it solved my problem on a similar heavy page load scenario.
