Enabling DPN on Legacy CAD Items for 12.0SP9

Hello, everybody

we did configuration of our 12.0SP9 according to this article (like for SP8)
https://community.aras.com/b/english/posts/enabling-dpn-on-legacy-cad-items-205775633
but we still do not have DPN for legacy files(

maybe somebody have the same issue and know what can be the issue?

what I`ve noticed is that new conversion tasks succeeded but new files do not upload to vault.

results are empty and no user data created
