Hi Marco,

Let me start by saying based on the information presented here, I don't believe this to be directly related to scripting. The `ClassCastException` makes sense if the `embeddings` mapping appeared to be a `float` type to the script.

Now, it's certainly odd that `embeddings` appeared as a `float` type, though. Are you able to reproduce this issue? And if so, would you please provide the steps you are taking to do so? Also when you say "reloading data" what do you mean by that?

Thanks!
