TypeError: expected a readable buffer object

I am running into the following error when I try to connect to an API using M2Crypto HTTPSConnection library using the GET method.

Traceback (most recent call last):
  File "osg-gridadmin-cert-request", line 665, in <module>
    status = check_quota_limit(request_count)
  File "osg-gridadmin-cert-request", line 543, in check_quota_limit
    conn.request('GET', arguments['quotaurl'], headers)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 941, in request
    self._send_request(method, url, body, headers)

    self.endheaders(body)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 937, in endheaders
    self._send_output(message_body)

    return m2.ssl_write_nbio(self.ssl, data)
TypeError: expected a readable buffer object

I am accessing the API using this code

conn = M2Crypto.httpslib.HTTPSConnection(arguments['host'],
            ssl_context=ssl_context)
        conn.request('GET', arguments['quotaurl'], headers)
        response = conn.getresponse()

Could you please help me with this problem?

See the error message

self._send_request(method, url, body, headers)

This indicates that you are passing "headers" where you are supposed to pass "body".

So, try calling 

conn.request('GET', arguments['quotaurl'], None, headers)
