Testing a HTTP API is working with a boto3 Lambda function-CodePudding

I'm not too sure how the formatting works with using json and boto3 in the same file. The function works how it should but I don't know how to get a response from an API without an Internal server error.

I don't know if it is permissions or the code is wrong.

import boto3
import json

def lambda_handler(event, context):
    client = boto3.resource('dynamodb')
    table = client.Table('Visit_Count')

    input = {'Visits': 1}

    table.put_item(Item=input)
    
    
    return {
        'statusCode': 200
        body: json.dumps("Hello, World!")
    }

CodePudding user response：

Instead of body it should be 'body'. Other than that you should check CloudWatch logs for any further lambda errors.

CodePudding user response：

Anon and Marcin were right, I just tried it and it worked Your Lambda role also need to have dynamodb:PutItem

import boto3
import json

def lambda_handler(event, context):
    client = boto3.resource('dynamodb')
    table = client.Table('Visit_Count')

    input = {'Visits': 1}

    table.put_item(Item=input)
    
    return {
        'statusCode': 200,
        'body': json.dumps('Hello from Lambda!')
    }
