从AWS SQS读取消息并将其放入AWS DynamoDB后，Python dict数据类型错误

Question

My use case is to take a JSON message from SQS body and insert data into DynamoDB Using the lambda function in python. the issue is I am able to read and print the JSON message from SQS queue into cloud watch log but when I try to insert the same JSON in dynamoDB it gives below Error

Invalid type for parameter Item, value: {'name': 2}, type: class 'str', valid types: class 'dict'

Below is the lambda code I am using and an error occurred at line number 12 where I am trying to insert using put_item

import json
import boto3

dynamodb = boto3.resource('dynamodb')
dynamoTable = dynamodb.Table('message')

def lambda_handler(event, context):
    for record in event['Records']:
        data1 = record["body"]
        jsondata1 = json.loads(data1)
        print(jsondata1)
        dynamoTable.put_item(Item=jsondata1)      

However, it is able to print the SQS JSON to cloud watch log as below

Answer 1

after so many R&D i am able to find the solution is by splitting the string by comma and then recreating an json which will create json of dict data type and not string

Below is the code for the same solution

import json
import boto3
import ast

dynamodb = boto3.resource('dynamodb')
dynamoTable = dynamodb.Table('message')

def lambda_handler(event, context):
    for record in event['Records']:
        data1 = record["body"]
        jsondata1 = json.loads(data1)
        mess1 = jsondata1["Message"]
        id = jsondata1["MessageId"]
        jsonmess = json.loads(mess1)
        s = jsonmess.replace("{" ,"")
        finalstring = s.replace("}" , "")
        split = finalstring.split(",")
        dict = {'messageID':id}
        for x in split:
            keyvalue = x.split(":")
            print(keyvalue)
            dict[keyvalue[0]]=keyvalue[1]
        dynamoTable.put_item(Item=dict)
