API Error: ComputerGroup is enabled for a site.

I created a test script that shows the behavior. It works the same on my test and production servers (9.91). This requires a little setup:

1. A smart group (or static group, I guess) assigned to a site.
2. A policy NOT assigned to a site, but scoped to the above smart group.

The script is below. Fill in the three strings at the top with your server, API account credentials, and the policy name from step #2.

If the test policy is in the same site as the smart group, the PUT call succeeds. Otherwise I get the error. This doesn't help me because in reality I'm working with policies scoped to multiple smart groups in multiple sites.

#!/usr/bin/python

import subprocess
from xml.etree import ElementTree

# build the base URL
base_url = 'https://your.jss:8443/JSSResource/policies/'
creds = 'TestUser:TestPassword'
policy_name = 'TestPolicy'

# get the policy data
xml = subprocess.check_output(['curl', '-s', '--user', creds, '-X', 'GET', '{base}name/{name}'.format(base=base_url, name=policy_name)])

# parse and edit XML. In this example we'll just disable the policy.
tree = ElementTree.fromstring(xml)
enabled = tree.find('general/enabled')
enabled.text='false'

# get the ID so we can use it in the update URL
pid = tree.findtext('general/id')

# regenerate XML
xml = ElementTree.tostring(tree)

# update policy via API
command = ['curl', '-s', '--user', creds, '-X', 'PUT', '-T', '-', '{base}id/{id}'.format(base=base_url,id=pid)]
shell = subprocess.Popen(command, stdin=subprocess.PIPE, stdout=subprocess.PIPE)
# pipe in the XML
shell.stdin.write(xml)
result = shell.communicate()[0]
shell.stdin.close()

#print the result, which should be the the ID of the policy (in XML form)
print result

Still not fixed. We ran into the same issue.
