's3.ServiceResource' не имеет атрибута 'get_object', когда я пытаюсь получить данные внутри json-файлов в S3 Bucket

Я начинающий пользователь AWS lambda. Как и с AWS в целом. Я пытаюсь сделать извлечение 20 ".json" из ведра S3. Поэтому я сделал следующее в лямбда-функции AmazonS3:

import json
import boto3

s3 = boto3.resource('s3')

def lambda_handler(event, context):
    bucket_name = 'jom-data'
    prefix = "reviews/ch/tmall"
    keys = []
    # list of 100 keys
    d = {}
    i = 0
    bucket = s3.Bucket(bucket_name)
    for object_summary in bucket.objects.filter(Prefix=prefix):
        key = object_summary.key
        print("key: ", key)
        if key.endswith(".json"):
            response = s3.get_object(Bucket=bucket, Key=key)
            print("response: ", response)
            content = response['Body']
            print("content: ", content)
            jsonObject = json.loads(content.read())
            
            d[i]["name"] = jsonObject["name"]
            d[i]["chinese_name"] = jsonObject["chinese_name"]
            d[i]["reviews"] = jsonObject["reviews"]
            print(jsonObject["name"])
            i += 1
            if i>=20:
                return d

Но она возвращается:
