It looks like we have additional indentation compared to old scripts. Maybe both work? However yaml requires proper indentation in order to work.

Seems okay, although we should test if the whitespace difference is significant?

This was done by my IDE, so I'm gonna trust that it's OK. But it's good to keep in mind if something goes wrong.
