'NoneType' object has no attribute 'startswith'

Start by reproducing the dss_plugin installation through the playbook, then inspect Ansible's module_common.py around recursive_finder and visit_ImportFrom, where the traceback reaches node.module.startswith. Compare the failing plugin's imports with the expected module format; done means the playbook installs the plugin without the NoneType traceback.

Hi guys

May I found help with this issue. It occurs when I try to install plugin throught playbook (dss_plugin).

Thanks in advance.

`The full traceback is:
