Are you having issues with Facebook contacts? "The operation couldn’t be completed. (CoreDAVHTTPStatusErrorDomain error 500.)"

Below is the error I am getting in the console from the Contacts program on my MacbookPro running Mountain Lion.

}

Accroding to that, it seems like there is an issue with Facebook's webdav server. What are some options for me to resolve this?

I tried visiting https://webdav.facebook.com/ It gave me a user/password prompt. I entered my username and login for Facebook, but it didn't work. Do I have to turn something on in Facebook to allow my MacbookPro to access the webdav.facebook.com?

Thanks
