I installed the latest build of delebiles repo on my new3ds yesterday. And I had the same issue as you. So I rolled back to the old version of of delebiles repo(cc81a86).Then I can use safea9lh installer v2 to install Aurora's fork.
Tried that but I still get the same error..
Edit: No, wait!
Edit 2: It worked! Thanks!
