Wrong brackets in getting the job cluster and process variables in fife_wrap
There is a line in fife_wrap that tries to get the job CLUSTER and PROCESS variables in JOBSUBJOBID is not set. That line is
description = "%s.%s" %(os.environ['CLUSTER'],os.environ('PROCESS'))
As you see, the brackets aren't consistent between getting cluster and process (one uses  and the other is ()).
