If the element is not found during MAX_DELAY period, error 476 is returned. If the page has slow construction (e.g. due to slow async JS calls), we can provide a custom API license
with the increased MAX_DELAY parameter. If you are interested in this option, please contact us on firstname.lastname@example.org with your Pdfcrowd username.
Error 458 is returned if the whole conversion does not finish in time limit for a single conversion (the limit is 60 seconds now).
I'd suggest you to enable debug log by setDebugLog
to see loading speed and add some debugging messages to your JS to see how your page is processed.
console.log('my start ' + new Date());
... do some stuff ...
console.log('my end ' + new Date());
