Thanks! This fixed the error I got

Something that's a bit more pythonic (IMO) would be to do something like this:

Suggested change

	try:
	iterator = iter(entity['rules'])
	except TypeError:
	continue
	if entity['rules']:

Then you'd have to move the following lines under the if:

kubernetes-rbac-audit/ExtensiveRoleCheck.py

Lines 50 to 61 in d933394

	for rule in entity['rules']:
	if not rule.get('resources', None):
	continue
	self.get_read_secrets(rule, role_name)
	self.clusteradmin_role(rule, role_name)
	self.any_resources(rule, role_name)
	self.any_verb(rule, role_name)
	self.high_risk_roles(rule, role_name)
	self.role_and_roleBindings(rule, role_name)
	self.create_pods(rule, role_name)
	self.pods_exec(rule, role_name)
	self.pods_attach(rule, role_name)

That way you're just checking to see if there are any results (since None is falsy), and it'll skip over the iterating if there are none.

Thanks for finding this though @0xz00n, seeing this PR made it easy for me to fix on my side 😁
