Rest API fails to properly utilize the base_url when specified.

[Cohbra11]

This code was taken directly from the tutorial: https://docs.cdp.coinbase.com/advanced-trade/docs/sdk-rest-client-trade

The code works when base_url=base_url is omitted from the RESTClient() class.

Ultimatetly I need to test with the sandbox endpoint https://api-sandbox.coinbase.com

# This is a summary of all the code for this tutorial
import os
from coinbase.rest import RESTClient
from json import dumps
import math

api_key = "organizations/*******************/apiKeys/****************************"
api_secret = "-----BEGIN EC PRIVATE KEY-----\n*************************\n***********************8==\n-----END EC PRIVATE KEY-----\n"
base_url = 'https://api.coinbase.com'

client = RESTClient(api_key=api_key, api_secret=api_secret, **_base_url=base_url_**)

product = client.get_product("BTC-USD")
btc_usd_price = float(product["price"])
adjusted_btc_usd_price = str(math.floor(btc_usd_price - (btc_usd_price * 0.05)))

order = client.limit_order_gtc_buy(
    client_order_id="00000002",
    product_id="BTC-USD",
    base_size="0.0002",
    limit_price=adjusted_btc_usd_price
)

if order['success']:
    order_id = order['success_response']['order_id']
    client.cancel_orders(order_ids=[order_id])
else:
    error_response = order['error_response']
    print(error_response)
