Hi,
when i run the mock test to validate the billing-event,
#serverless invoke local --function billing --path mocks/billing-event.json

i get this:

Serverless: DOTENV: Loading environment variables from .env:
Serverless: 	 - STRIPE_SECRET_KEY

     For debugging logs, run again after setting the "SLS_DEBUG=*" environment variable.

It’s really hard to know whats going on based on that. It seems like it might be a config related issue. You can try prefixing your command with SLS_DEBUG=* to get more debug info.
