1. What operation are you trying to do?

2. What permissions do you have on the document?

3. Which groups does this user belong to?

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.

What happens if you try to use the document() function on that document ID from a blank expression rule editor?
