Codecrafters ping command is not working

Hi, i’m trying to setup repository locally. i cloned it. went into the folder. installed codecrafters CLI. and now trying codecrafters ping to submit the step.

But i got following error :

abhijit@Abhijits-MacBook-Air codecrafters-shell-cpp % codecrafters ping
Unknown command 'ping'. Did you mean to run `codecrafters test`?

Run `codecrafters help` for a list of available commands.

Appreciate any thoughts

Problem is solved. Actually i had an old version of codecrafters. i did brew remove codecrafter` and then reinstalled it again.
