Salt State Exception: OSError 2

1 August 2015

I was scratching my head on this one. A salt minion reported this in it's log file and some states were not applied to my Windows Virtual Machine.

2015-07-15 22:47:52,427 [salt.state       ][ERROR   ] An exception occurred in this state: Traceback (most recent call last):
  File "salt/state.py", line 1379, in call

It then dawned on me. I recently wrote a salt state to clean the NUnit shadowcache.

nunit_shadow_cache:
  file.absent:
    - name: 'C:/users/buildUser/appData/local/temp'

It looks as though it was removing all salt temp files causing the above error. I changed the path to delete the nunit20 folder in the temp folder.s

nunit_shadow_cache:
  file.absent:
    - name: 'C:/users/buildUser/appData/local/temp/nunit20'

Happy days!
