why woocommerce REST api is returning empty value

We updated the woo commerce plugin latest version as 3.4 in local and test server.

Woo Rest API is not getting value properly. It is getting an empty value.

when we print the JSON value and it is getting below error in woo commerce.

ex:
res=wcapi.get(“orders/18647”)
print res.json()

raise ValueError(“No JSON object could be decoded”)
ValueError: No JSON object could be decoded

Code:

wcapi = API(
   url="https://www.example.com/",
   consumer_key="xxxx",
   consumer_secret="yyyy",
   wp_api=True,
   version="wc/v2",
   query_string_auth= True,
)

if(wcapi):
	print(wcapi)
res=wcapi.get("")
print res
print res.status_code
print res.headers['content-type']
if(res.text==""):
	print "Empty data "
else:
	print res.text

Output:

<woocommerce.api.API object at 0x7f27860e66d0>
<Response [200]>
200
application/json; charset=UTF-8
Empty data
