When looking up an attribute with .attr(), the name of the attribute should be lowercased before looking up in .attribs object.

Unless I missed something, the documentation doesn't explain how to query document metadata (searching "site:montferret.dev metadata" through Google returned nothing, neither did grepping the source code).

I tried variations of //meta[property='og:url']::attr(content), with or without the leading //, and with or without the `attr(conte

For example Error: PuppeteerCrawler: handlePageFunction timed out. could contain instruction how to increase the timeout.
