AttributeError: 'str' object has no attribute 'get' - wrapper.py

[bissli82]

Expected Behavior

Hi all,@joeyzhao2018 , I'm getting a few error messages coming from the wrapper.py,
It comes as info and not as an error, that's my guess to why it was missed for awhile.
I assume this is because our lambda function returns as string and not an object(json?) which the extension expect so self.response is an str.

I think the issue was introduced by this PR

Actual Behavior

Steps to Reproduce the Problem

As far as I can see, any lambda run which returns a string
