我正在尝试使用Amplify上传我的Lambda函数，当前遇到错误。我已经在Lambda本身中测试了该功能，并且运行良好，当我尝试运行测试（放大模拟功能）或尝试将其推送到云时，我只是遇到问题。
我收到以下错误：

这是我尝试上传的以下代码，请注意，它在Lambda本身中正常工作，并且需要IAM角色才能访问两个DynamoDB数据库：
from __future__ import print_function # Python 2/3 compatibility
import boto3
import json
from decimal import Decimal
from boto3.dynamodb.conditions import Key, Attr
dynamodb = boto3.resource('dynamodb')
RatingTable = dynamodb.Table('RatingsTable')
ChipRatingTable = dynamodb.Table('ChipRatingTable')
def lambda_handler(event, context):
response = RatingTable.scan(
FilterExpression=Attr('id').exists()
)
items = response['Items']
def parseData(items): #Used to turn the DynamoDB scan into a 2D array
parsed_item_list = {}
for item in items:
assetId = str(item.get('assetId'))
rating = int(item.get('rating'))
if assetId not in parsed_item_list:
parsed_item_list[assetId] = []
parsed_item_list[assetId].append(rating)
return parsed_item_list
data = parseData(items)
def updateChipRating(asset, averageRating, RateCount, rating5, rating4, rating3, rating2, rating1) :
updateItem = ChipRatingTable.update_item(
Key={

},

)
#Makes the calculation
for x in data :

sum = 0
for y in range(len(data[x])) :
sum += data[x][y]
if data[x][y] == 5 :
rating5 = rating5 + 1
elif data[x][y] == 4 :
rating4 = rating4 + 1
elif data[x][y] == 3 :
rating3 = rating3 + 1
elif data[x][y] == 2 :
rating2 = rating2 + 1
elif data[x][y] == 1 :
rating1 = rating1 + 1
print(x)
print(rating5,rating4,rating3,rating2,rating1)
#Average caluclation
average = sum / len(data[x])
averageRating = round(average, 1)
RateCount = len(data[x])
updateChipRating(x, averageRating, RateCount, rating5, rating4, rating3, rating2, rating1)
任何帮助将不胜感激！谢谢！
