Page not found

Error message

Page not found

What it means

In the PDF worker's docInfo$ loop, thrown when doc.page(i) returns null for an index below pageCount, meaning the underlying PDF document reports a page count but cannot supply that page — a corrupted or inconsistent document.

Solutions

1. Request a page number within the document's page range.
2. Refresh the page count after loading the document.

When it happens

Trigger: Thrown while collecting document metadata in the PDF worker when doc.page(i) returns null for an index below the reported pageCount.

Common situations: Triggered by a malformed PDF whose pages cannot all be accessed during loading. Re-export or repair the PDF and upload it again.
