Improve error logging #94
Description
Background
The Python awslambdaric v2.0.0 library works perfectly in conjunction with awslambdarie in local dev, and it usually works great in 'proper' Lambda, but unfortunately not all the time. When I invoke some particular in-house libraries while running in Lambda, the invocation dies without giving an insightful reason.
Problem
The provided error 'Runtime exited with error: exit status 1' does not help me debug why a fault is happening.
Suggested fixes
- Document what could cause awslambdaric / Lambda to die and return a runtime exiterror 1
- Provide detailed outputs in the execution log about what has just caused the fault
