Yahoo Callback Domain Issue

While creating a new app on Yahoo Developers Network the field (i.e. Callback Domain) is not accepting any URL having slash ('/') in it, but previously it is taking the URLs with slashes.

Error thrown:

Application Create failed. Scopes creation failed when creating App: 507 - {"domain_name":{"errors":[{"code":2402,"message":"Invalid domain name: mobile.local.com/"}]}}

My redirect URL contains path for a sub-page and it is not possible for me to remove all the slashes from my callback domain URL.

What can I do in such case?

Please help.
