JSONDecodeError in Google Translate API

问题

I am trying to translate some data using googletrans python library. The below program first worked fine and after processing some requests it gives a JSONDecodeError. After some searching I found that Google may be blocking my IP address after a limited number of requests. Is this the actual problem? If then is there a solution? (Ex: using a vpn). Or else is there a fault in my code that causes the error?

My Code

import glob
import errno
import json
from googletrans import Translator
from pymongo import MongoClient

client = MongoClient('mongodb://localhost:27017/')
db = client.knowledge
en_entities = db.en_entities
ta_entities = db.ta_entities

translator = Translator()

path = '../data/DialogFlow Data/entities/*entries*.json'
files = glob.glob(path)
for name in files:
    try:
        with open(name) as f:
            entities = json.load(f)
            for entity in entities:
                synonyms = []
                translations = translator.translate(entity['synonyms'], dest='ta')
                for translation in translations:
                    synonyms.append(translation.text)
                dic = {'value': entity['value'], 'synonyms': synonyms}
                ta_entities.insert_one(dic)
    except IOError as exc:
        if exc.errno != errno.EISDIR:
            raise

Error
