Creating a new repo inside an organization Edited

[amunn]

I have an organization linked to my GitHub account. Sourcetree for MacOS (v 4.0.1) has been granted access to it, and I can push commits to existing repos in the organization. However, when I try to create a new repo from a local folder using Sourcetree the creation fails with the very cryptic message below:

Create repository failed. Error contents:

    message: Not Found

    https://developer.github.com/v3/repos/#create

When I create the repo I am able to choose the organization as the owner of the repo from the dropdown menu that appears during the create remote part of the process.   

Is there a way to get this to work correctly?
