But an instance of Async[ConnectionIO] has gone. In the meanwhile there was an instance of LiftIO[ConnectionIO], but it is also gone. https://stackoverflow.com/a/50481203 states that the following approach worked:
catsIO.to[ConnectionIO]but I receive the error \"No given instance of type cats.effect.LiftIO[doobie.ConnectionIO] was found for parameter F of method to in class IO\". I cannot find an instance of LiftIO.
Does anyone know of how to turn an instance of Cats IO to ConnectionIO?
