See the comments around this post. It seems that unlike other languages, YAML needs to be structured with leading spaces in front of field names, properties, etc. for forms to be parsed properly.
All of the code examples show the indenting, but I thought this was for readability and not a requirement. It's easy to break a form and hard to spot why it's not working if you're not aware of this.
This is not mentioned anywhere in the documentation.
