Not sure what is to blame for the errors here..

I tried creating an OAuth application and using both its name and clientid but neither worked (I get a bad credentials message instead).

Depending on the value of Application Name, I get an invalid format error.

The repository I'm trying to work against is within & owned by an Organization.
