A lambda to unpack the POST body (assumed to be JSON) and log it to cloudwatch

LambdaLogger.js

exports.handler = async (event, ctx, callback) => {
    console.log({app:"unknown", env: "unknown", ...(JSON.parse(event.body))});
    
     var response = {
        "statusCode": 200,
        "body": JSON.stringify({result:"ok"}),
        "isBase64Encoded": false
    };
    callback(null,response);
};

... should probably handle malformed requests a bit more sensibly.
