Steps to reproduce

Create a template with a renderlet editable and pass some custom parameters as stated in the docs.

Actual Behavior

When you try to fetch them in the controller from the request query bag as stated in the docs, the bag is empty.

Instead of being in the query bag, they are in the attributes bag and must be accessed via $request->attributes->get('yourKey')

Expected Behavior

Being able to fetch them from the query bag like $request->query->get('yourKey').
