Hey has anyone else hit this? I'm trying to get rocket working with templating now that static folder is a thing, but I'm hitting compilation errors almost straight away... created new project with cargo shuttle init --rocket Added the static folder to my shuttle_service::main - see below. cargo check fails thus: error[E0554]:
