When you don't know, ask a question but don't raise an issue. It's not visible in the message you posted because markdown doesn't display consecutive spaces, but in the log you should see that you have extra spaces.

Don't raise issues so lihgtly in the future and please read this: https://docs.codewars.com/training/troubleshooting/
