"""
This test replicates a bug where if a logic function were decorated
and we sendt a json body request that contained parameters not in
the logic function's signature it would cause a TypeError similar to
the following for the logic function defined in this test:
TypeError: logic() got an unexpected keyword argument 'e'
This test verifies if a logic function uses the **kwargs functionality
that we pass along those to the logic function in addition to any
other positional or keyword arguments.
