I am trying to use AWS Lambda, along with API Gateway to send some JSON strings between clients.

Currently, I can only get it to send a single value, for example:

{"action":"sendMessage", "message": "hello"}

But i would really like to be able to send something like:

{"action":"sendMessage", "message": {"status1": "hello"}}

And for the sent message to be: {“status1”: “hello”}

Unfortunately I’m stuck on the first example, of only being able to send “hello”, nothing else passes.

This is code I’m using for my websocket send:

import json
import boto3
import os

dynamodb = boto3.client('dynamodb')


def lambda_handler(event, context):
    message = json.loads(event['body'])['message']
    paginator = dynamodb.get_paginator('scan')
    connectionIds = []

    apigatewaymanagementapi = boto3.client(
        'apigatewaymanagementapi', 
        endpoint_url = "https://" + event["requestContext"]["domainName"] + "/" + event["requestContext"]["stage"]
    )

    for page in paginator.paginate(TableName=os.environ['WEBSOCKET_TABLE']):
        connectionIds.extend(page['Items'])

    for connectionId in connectionIds:
        apigatewaymanagementapi.post_to_connection(
            Data=message,
            ConnectionId=connectionId['connectionId']['S']
        )

    return {}
