Document not opened

Error message

Document not opened

What it means

A document-availability guard inside the pdf.worker's docInfo$ pipeline: doc$ (a shared ReplaySubject of the opened PDF document) emitted a falsy value, meaning open() was never called with data or the document failed/closed before metadata extraction. It fires when metadata (page count/sizes) is requested before a document has been successfully opened in the worker backend.

Solutions

1. Open the document in the PDF worker before requesting pages.
2. Re-initialize the renderer if the document was closed.

When it happens

Trigger: Thrown in the PDF renderer worker when viewer.open returns no document for the provided binary, or when docInfo/render is requested while doc$ holds no opened document.

Common situations: Occurs when a PDF fails to open in the viewer, typically due to corrupted or unsupported PDF data. Re-upload a valid PDF file and try again.
