on
Called when InstantPdfDocument has detected data corruption.
Receiving this callback means any further interaction with the sender’s document are destined to fail. You can copy the document package aside for forensic purposes, but you will — eventually — have to purge its storage, and download it anew.
Because this situation means the document has become unusable, it will invalidate itself immediately after this method returns.
Parameters
instant
Document that has detected data corruption.
