Similar issue was faced when Ansible version was upgraded from version 2.3 to 2.4.

This was the error faced:

"module_stderr": "Traceback (most recent cmp/ansible_TEdNxx/ansible_module_bigip_pool.py\", line 237, in \n    from ansible.module_utils.f5_utils import (\nImportError: cannotexpectedHTTPError\n", "module_stdout": "", "msg": "MODULE FAILURE", "rc": 0}
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ImportError: cannot import name iControlUnex

Fix is by installing f5-sdk. You can do a pip install f5-sdk. Somehow this became a requirement after updating Ansible to version 2.4

    [root@ansible-controller f5] pip install f5-sdk
