Put Json to DynamoDB item

I am trying to update a json response to an item in AWS DynamoDB and getting below error. Could someone please help on this

import boto3
import json

dynamoDB = boto3.client('dynamodb')

def lambda_handler(event, context):
    testinfo = {"Smile":{"Confidence": '99.8970947265625',"Value": 
"True"}}
    dynamoDB.put_item(TableName='DetectedInfo',Item={'DateTime': 
'12282018','Info': json.dumps(testinfo)})

Error:

ParamValidationError: Parameter validation failed: Invalid type for parameter Item.Info, value: [{"Smile": {"Confidence": "99.8970947265625", "Value": "True"}}], type: , valid types: Invalid type for parameter Item.DateTime, value: 12132018, type: , valid types:

It has to be of form:

dynamoDB.put_item(TableName='DetectedInfo',
    Item={
    'DateTime': {
    'N':'12282018'},
    'Info': {
    'S':json.dumps(testinfo)}
    })

Here N,S is the type of variable.You need to check allowed data types in aws documentation and apply accordingly.
