Is "#$" a literal string?  You might want to substitute* the correct
directory in there after running package-generate-autoloads.

As for make-directory-autoloads vs. loaddefs-generate, IIRC both have
the same signature, so you could make this work with both the non-
deprecated function in Emacs 28 and the new one added in Emacs 29.
