Use the REST proxy on the BIG-IQ system ERROR

Hello,

I'm working in a local environment trying to use the REST proxy on the BIG-IQ system with the objective of acquire certain info of a BIG-IP. 

Once I've obtained the BIG-IQ token, discovered the BIG-IP device, enabled the REST-PROXY feature and obtained the BIG-IP uuid (4ad12733-95ea-47b0-a562-dd6ac6da5adc), which basically consists on following the steps found on that website Enabling BIG-IQ Centralized Management as a REST proxy for BIG-IP devices (f5.com); it is time to confirm that the BIGIP has been discovered and included into the BIGIP devices group with the code below.

headers = {
    'X-F5-Auth-Token': f'{token}'
}

# Request to confirm that the BIGIP was discovered and is included in the cm-bigip-allDevices group
url_id = "https://192.168.1.44/mgmt/shared/resolver/device-groups/cm-bigip-allDevices/devices/4ad12733-95ea-47b0-a562-dd6ac6da5adc"
response_id = requests.get(url_id, auth=HTTPBasicAuth('admin', 'psw'), headers=headers, verify=False)

The problem is that when I execute that, there is an output variable that states that "state": "PENDING", when that should be  "state": "ACTIVE".  Why? Do I left something? Am I doing something wrong?

Thanks in advance
