screenshot agent timed out on infinite scroll locale pages

TL;DR

Fixes the screenshot agent timing out on infinite-scroll pages in locale QA. Scroll to a fixed depth or stub the feed before capturing. Use when locale screenshots time out on feeds. Not for static pages.

The error

Screenshot agent timed out after 120s scrolling the localized activity feed.

Fix it

Step 1: Confirm the infinite scroll

node -e "console.log('the feed loads more items on every scroll; the agent never reaches the bottom')"

Expected: You confirm the page never settles.

Step 2: Cap the scroll depth

node -e "console.log('scroll a fixed number of viewports, then capture')"

Expected: The agent captures a bounded page.

Step 3: Re-run the locale suite

node -e "console.log('confirm screenshots complete for every locale')"

Expected: The suite finishes.

When to use this

• Screenshot capture times out on feed pages
• The page loads content forever on scroll

When NOT to use this

• Static pages time out, check the page load
• Screenshots capture but look wrong, check the rendering

Tool and version compatibility

• Playwright and Puppeteer
• Any infinite-scroll feed

Variant phrasings

timeout only in some locales

Those locales have more content. The cap must be content-independent.

screenshots differ run to run

Stub the feed data so captures are deterministic.

Why it happens

Infinite scroll never reaches a settled state, so an agent waiting for network idle or page bottom waits forever. Bounding the scroll gives the agent a finish line.

Edge cases

• Lazy-loaded images need a settle wait after the scroll cap
• Virtualized lists render only the viewport; capture scrolled positions separately
• Locale changes the item count, so depth must not depend on content
