get_a_record ValueError: No JSON object could be decoded

[seph3]

Environment:
Infoblox WAPI 2.6.1
ansible-playbook 2.4.2.0
python version = 2.7.5 (default, May 3 2017, 07:55:04) [GCC 4.8.5 20150623 (Red Hat 4.8.5-14)]

For bypass https certificate validation I modified the inflobox.py:

182 try:
183     import requests
184 #    requests.packages.urllib3.disable_warnings()
185     HAS_REQUESTS = True
186 except ImportError:
187     HAS_REQUESTS = False
188
189 import urllib3
190 urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

Now I receive a error when try to get_a_record

The full traceback is:
