Check if a document exists in Appian

Question

So I have an interface that has links to documents that have been uploaded. However, the documents don't exist until after they've gone through a process model (or rather they're a temp file that you can't reference at that time). What I'd like to do is disable those links if the documents haven't been put into the system yet, but I am not sure how to check to see if the document exists in the system yet or not. Is there a function or something that can test a doc id to see if it's valid or not?

findcontentbyattribute(
 searchAllContent: true,
 contentType: "document",
 attributeName: "name",
 searchCriteria: "docName"
) 
 findcontentbyattribute() is part of Content Tools plug-in , It should be available to most env. please do deploy if not.

you can also use the below logic to find the object exist in the system 
 a!localVariables(
 local!objectDetails: if(
 a!isNullOrEmpty(ri!objectId),
 "No object with this ID has been found",
 getcontentobjectdetailsbyid(ri!objectId)
 ),
 if(
 tostring(local!objectDetails) = "No object with this ID has been found",
 false,
 true
 )
)

getcontentobjectdetailsbyid(id)

I noticed the "invactive" typo and filed a bug report for it with the plug-in authors... 5 years ago maybe? maybe more? 
 Anyway here's my expression rule that tests whether any given ID is an *existing, inactive document*. 
 and(
 rule!UTIL_docExists(ri!doc), /* does "not null or 0" check, checks using "is [document] object exists" function; if all are true, returns true */
 find(
 /*"State: Invactive Published",*/
 /* note misspelling above. instead, checking against the correctly-spelled output for Active documents */
 "State: Active Published",
 getcontentobjectdetailsbyid(ri!doc)
 ) = 0
)
