Hi everyone,
I ran into the following runtime error when accessing a bookmark destination (from a namedDestination):
Unfortunately I cann't share the original PDF (probably malformed), but it opens correctly on other viewers.
This PR fixes the issue by adding a simple defensive type check before casting the destination value to PdfNumber, preventing invalid casts when the destination contains PdfNull (or anything else)
