Scala Quill database - getting logging error

Question

I am trying to use the scala library quill(http://getquill.io) for querying a mysql database but I get an error from Hikari where the logger can be created.

The error:

This is the code:

package com.vogonjeltz

object quilltest extends App {

  lazy val db = source(new JdbcSourceConfig[MySQLDialect, SnakeCase]("db"))

  case class User (auth_forename: String)

  val q = quote {
    query[User].filter(_.auth_forename == "Freddie")
  }
  println(db.run(q))
