Redis#exists(key) will return an Integer in redis-rb 4.3. exists? returns a boolean, you should use it instead. To opt-in to the new behavior now you can set Redis.exists_returns_integer = true. To disable this message and keep the current (boolean) behaviour of 'exists' you can set Redis.exists_returns_integer = false, but this option will be removed in 5.0.
