Python2.7 + Google BigQuery + HTTPLIB2 - Proxy Error

Good afternoon,

I'm using google BigQuery for python2.7. I need to set the proxy for such access and so I use the httplib2 library as per the code below:

# Imports the Google Cloud client library
from google.cloud import bigquery
import uuid
import os 
import urllib2
import httplib2
from httplib2 import socks
import requests
import google.auth

os.environ['GOOGLE_APPLICATION_CREDENTIALS'] = 'MeuArquivo.json'
credentials, _ = google.auth.default()

http_client = httplib2.Http(proxy_info = httplib2.ProxyInfo(socks.PROXY_TYPE_SOCKS5, 'http://minhaUrl.com.br', 80))
v_bqClient = bigquery.Client(_http=http_client, credentials=credentials)

v_sql = "select count(1) as qtd "
v_sql += "from  minhaTabelaExemplo "
v_sql += "limit 10 "

v_queryJob = v_bqClient.query(v_sql)
for row in v_queryJob.result():  # Waits for job to complete.
    print(row)

But I always get error on line v_queryJob = v_bqClient.query(v_sql) . Below the error:

Traceback (most recent call last):

I'm not sure how to proceed to resolve this error. Did anyone ever go through a similar error and could you help?
