Hello, it seems the cause of the error is that the lambda event is empty (None). Any ideas why it might be set to None?

hello, I just started And I can't figure it out. I had never encountered an incident like this before.

Hi @suwat-netprom - looking at your report I suspect this library doesn't work with serverless-wsgi. This is because serverless-wsgi converts the incoming lambda event into a standard WSGI event.

We can of course fix this logic to not cause an error, but this library is effectively predicated on having the event object accessible, so without that I'm not sure we'll able to fundamentally help. We can consider this a feature request for now.
