Repository List Sort not working

I am trying to get sorted repository list, but it seems the request is not considering other params that I passed to the `repos` object. I am getting a default list all the time which is sorted by `full_name`.
PFB my code -

```ruby
github.repos(user: user_name, repo: repo_name, sort: 'pushed', direction: 'desc')
```
> Note: `github` is an object of `Github::Client`
