This looks like python 2 code and needs updating to support python 3 because Python 2 runtime is no longer an options on AWS Lambda. On python 3 runtime get the following error,

AttributeError: module 'urllib' has no attribute 'unquote_plus'

For a quick fix, import like this:
from urllib.parse import unquote_plus
