I'm afraid of asking this kind of basic question.

I want to manage database config by ENV, but I get an error.

This is my code:

(defconfig :common
    `(:databases ((:maindb :mysql
                      :database-name (uiop:getenv "DATABASE_NAME")
                      :host (uiop:getenv "DATABASE_HOST")
                      :port (uiop:getenv "DATABASE_PORT")
                      :username (uiop:getenv "DATABASE_USERNAME")
                      :password (uiop:getenv "DATABASE_PASSWORD")))))

This is sbcl error:

 1(GETENV DATABASE_HOST) is not a Lisp string or pointer.
