Error when writing security groups for clusters using spot instances

I have run into errors when trying to use spot instances for a starcluster. The errors appear to be specific to when spot instances are requested.

The configuration in question is

### THIS BLOCK IS UNSUCCESSFUL AND PROMPTS THE ERROR BELOW
# add test cluster
[cluster test]
# Declares that this cluster uses smallcluster as defaults
EXTENDS=smallcluster
# number of ec2 instances to launch
CLUSTER_SIZE = 10
# choose instance type
NODE_INSTANCE_TYPE = m1.large
# Set SPOT instance bid
SPOT_BID = 0.02 #IF THIS LINE IS COMMENTED OUT, NO ERRORS ARE ENCOUNTERED
#add volumes of persistant storage
VOLUMES = test

The error output is the following:

Any idea why spot instances would be throwing this error? Thanks for your effort! I might try some difference parameters to see if any other variations will work.
