Dropbox -> Google Drive

I am trying to create an automation that identifies a new file uploaded to Dropbox folder (works fine) which then uploads the same file to google drive.
Through mapping RES2URL I can get a file uploaded, however it is corrupted (pdf). None of the other links identified (including sharable URL) result in anythign being uploaded to google drive.
What is going wrong here?
I'm assuming it has something to do with Res2 URL opening the file in a dropbox container and Res2 Shareable Link redirecting to a longer URL?
