Error message

could not get page info

What it means

newPageState fails when browser.Page.Info() returns an error, meaning the browser could not report the current page's URL/title (e.g. page crashed, closed, navigation in progress, or CDP call failed). The wrap annotates the underlying browser error before it propagates to getPageHash/crawlFn.

Solutions

1. Check the wrapped cause: if the browser page was closed or crashed, recreate the page before retrying
2. Log the underlying error to distinguish transient navigation races from a dead browser session
3. Retry page.Info() once if the failure occurred during an in-flight navigation
4. Skip this page state and let the crawler continue with other queued actions
