I see, thanks a lot for the quick response. The reason I opened an issue first in github for this is that I think it should be possible to get a read journal without this conversion. But for now this is sufficient for what I’m trying to do. Btw… I also found it in the docs now… sorry for bothering you.
Just some notes after trying it: it is actually not called Adapter.toClassic() it is called Adapter.toUntyped(). There is no toClassic() (at least in in Akka 2.5.26)
