Runtime.MarshalError in python

Question

I am Getting this error. I am executing code of aws lambda function using python 3.7 to know quicksight dashboard version. Thanks in advance!

errorMessage: "Unable to marshal response: Object of type datetime is not JSON serializable",

errorType : "Runtime.MarshalError"

Code-

import boto3
import time
import sys
client = boto3.client('quicksight')
def lambda_handler(event, context):
    response = client.list_dashboard_versions(AwsAccountId='11111', DashboardId='2222',MaxResults=10)
    return response

Answer 1

I quick fix could be:

import boto3
import time
import sys

import json

client = boto3.client('quicksight')

def lambda_handler(event, context):
    response = client.list_dashboard_versions(AwsAccountId='11111', DashboardId='2222',MaxResults=10)

    return json.dumps(response, default=str)
