running lamdba invoke throws this error:

YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.

Steps to replicate:

• create pipenv
• pipenv install python-lambda
• create event.json
• edit yaml file
• create python service.py
• run lambda invoke -v

It's not fatal, the service runs fine.
