Hello, When I launch my Dancer2 application (Version 0.158000), I have the following message: Engine 'JSON' is not supported. at (eval 88) line 22. In my config.yml, I have: ... engines: JSON: allow_blessed: '1' canonical: '1' convert_blessed: '1' ... All works fine under Dancer2 version 0.153002 Why ? Thanks, Jean-Marc
