Hi @janm2 ,

Could you try to replace your code with uppercase "MOVE" (or "DELETE" depending on which you want to use)?
I know that it sounds silly, but I've encounter several times cases where case-sensitive was shooting me in face 🙂

And since you wrote that there is no archive_mode set for the data, that makes me wonder if this is due to this reason 😄

.option("cloudfiles.cleanSource", "MOVE")
