Bamboo NUnit System.InvalidOperationException

[Ryan Holzum]

I'm trying to get Bamboo to Run NUnit tests.  I'm currently getting this error.  I've tried giving the task my sln, my csproj, I even added a step before hand to build the solution, and tried giving the NUnit task the compiled dll, they all resulted in below.  It's pretty much an empty NUnit test project, that has a single test that asserts 1 = 1.

And idea on what to try next?

Incase anyone runs against this problem, I had a small error in the file path to the DLL.  However, the big problem is is I was using NUnit.exe instead of NUnit-console.exe  Once I changed that it worked.
