KeyboardInterrupt:

problem is in the requester.py file, where the requester function returns str response if it fails to make a successful HTTP request. hence the AttributeError: 'str' object has no attribute 'headers' error.

def requester(request, payload={}):
    """
    central function for making http requests
    returns str on error otherwise response object of requests library
    """

So in the meantime, you can keep this in mind, while creating a pull request to fix this error.
