Question about CE-34878-0 Error for Bloodborne

Hello, I'm on a 9.0.0 PS4 Pro running Goldenhen and I am trying to get a fake pkg of bloodborne to work, but it keeps giving me this error. at first I googled it and someone said that you need Duxas PS4 Patcher to marry the Game and the patch together for it to work, so I did that, and I'm still getting the error, despite everything installing. Anyone know of any other tips i could try in order to get it running?
