Hey aakash- hope things are going well for y'all.

I had a similar issue when dealing with a custom plug-in that generates an excel file - i noticed eventually that it always gets the original version of an uploaded template and disregards subsequent new versions. I believe this is a bug in the plug-in in question, and it sounds from your description like Content Tools might have a similar issue.

Luckily I stumbled on the following code snippet which uses a bit of a brute-force approach to look up the document id for the latest version of a file with multiple versions (i think in the Appian FS, the updated version is given its own unique id, but the original ID essentially becomes a pointer to the new ID, which helps explain why certain functionality misses this and still uses the original referenced document).

We have this as a utility expression rule i.e. `RULE_Utility_getLatestDocumentVersion`, with an input for Document and an optional input for RootFolder (which i think can usually be omitted).

todocument(
  tointeger(
    index(
      findcontentbyattribute(
        searchAllContent: false(),
        contentType: "document",
        attributeName: "name",
        searchCriteria: document(ri!document, "name"),
        rootFolder: rule!RULE_General_replaceNull(
          ri!rootFolder,
          document(ri!document, "folderId")
        )
      ),
      1,
      null()
    )
  )
)
