Project Import failed

I have installed mercurial and created a repository. I am trying to create a project in upsource and trying to add that repository in my local machine, but I getting an error as under. I have specified repository url as "http://localhost:8000/"  from tortoise hg. On testing connection, the connection is successful but not able to import project in upsource. Any help is greatly appreciated.
