You might need to take a deeper dive into what you're trying to have "document()" do here. In my experience, that error is almost always seen when attempting to call it on a document ID that's freshly-uploaded into a File Upload Field on a form that has not been Submitted - and thus it's still sitting in the "appian-only back-end purgatory" space, instead of having been moved to the normal Appian Filesystem where it's available for general use. I suppose you might also get the same error in the case of a user having severe lack-of-permission, but you say you've already checked for that.
Thank you for the details mike
Earlier the document in appian system was deleted and db and process instances still have the deleted document id later i have uploaded the document manually and updated the document id in table and in active instances. after doing this again the same error was occurred
What happens if you try to use the document() function on that document ID from a blank expression rule editor?
