Не уверен, где я делаю не так.Ниже мой лямбда-код и шаблон облачной информации.
Ниже представлена моя лямбда-функция:
import os
import boto3
def quickstart_lambda_handler(event, context):
print("event={}".format(event)) # nothing shows as k1:v1
print(os.environ) # nothing show in output as var1
print("environment variable var1: " + os.environ['var1'])
json_str = "{\"a1\":\"b1\"}"
bucket_name = "my-s3-bucket"
file_name = "qs.json"
s3_path = "cf-quickstart/" + file_name
s3 = boto3.resource("s3")
s3.Bucket(bucket_name).put_object(Key=s3_path, Body=json_str)
print("object stored in s3")
return s3_path
Мой шаблон формирования облака такой же, как и ниже для лямбда-функции и связанного с ней правила.

Пожалуйста, дайте мне знать, где я неправ.Спасибо за помощь.
