Create node fails

With the f5-common-python sdk:

import requests
from f5.bigip import ManagementRoot

 Ignore SSL Errors
requests.packages.urllib3.disable_warnings()

 Instantiate the BIG-IP
b = ManagementRoot('192.168.102.5', 'admin', 'admin', token=True)

 Create a node with IP address
node1 = b.tm.ltm.nodes.node.create(name='node1', address='192.168.102.100', partition='Common')

 Create a node with FQDN
node2 = b.tm.ltm.nodes.node.create(name='node2', address='any6', fqdn={'tmName': 'node2.test.local'}, partition='Common')

Without the sdk:

import requests, json

 Ignore SSL Errors
requests.packages.urllib3.disable_warnings()


 Get Token Function
def get_token(bigip, url, creds):
    payload = {}
    payload['username'] = creds[0]
    payload['password'] = creds[1]
    payload['loginProviderName'] = 'tmos'

    token = bigip.post(url, json.dumps(payload)).json()

    return token['token']['token']


 Set up request session
b = requests.session()
b.headers.update({'Content-Type': 'application/json'})
b.auth = ('admin', 'admin')
b.verify = False
 Call token function to get token
token = get_token(b, 'https://192.168.102.5/mgmt/shared/authn/login',
                  ('admin', 'admin'))
 Update auth from basic to token
b.auth = None
b.headers.update({'X-F5-Auth-Token': token})

 Create a node with IP address
payload = {}
payload['name'] = 'node3'
payload['partition'] = 'Common'
payload['address'] = '192.168.102.101'
node3 = b.post('https://192.168.102.5/mgmt/tm/ltm/node', data=json.dumps(payload))

 Create a node with FQDN
payload = {}
fqdn = {'tmName': 'node4.test.local'}
payload['fqdn'] = fqdn
payload['name'] = 'node4'
payload['address'] = 'any6'
payload['partition'] = 'Common'
node4 = b.post('https://192.168.102.5/mgmt/tm/ltm/node', data=json.dumps(payload))
