AWS Lambda targerting CloudWatch Logs - amazon-web-services

Question

I tried to follow Using DynamoDB with Custom Alexa Skills - Dabble Lab #226 - YouTube video, had some issues that mostly I was able to fix. I guess I am just to new to AWS and Lambda. But I wonder if someone is able to explain me why I don't have CloudWatch Logs as target, as shown in the video and how I can fix that. When I try to save a movietitle alexa sais 'we cannot save your movie right now. Try again!'. Would be amazing If someone here could help me : )
My lambda code:
/* eslint-disable func-names */
/* eslint-disable no-console */
const Alexa = require('ask-sdk');
const dbHelper = require('./helpers/dbHelper');
const GENERAL_REPROMPT = "What would you like to do?";
const dynamoDBTableName = "dynamodb-starter";
const LaunchRequestHandler = {
canHandle(handlerInput) {
return handlerInput.requestEnvelope.request.type === 'LaunchRequest';
},
handle(handlerInput) {
const speechText = 'Hello there. What is your favourite movie? You can say add moviename to add your favourite movie or say list my movies to get your favourite movies.';
const repromptText = 'What would you like to do? You can say HELP to get available options';
return handlerInput.responseBuilder
.speak(speechText)
.reprompt(repromptText)
.getResponse();
},
};
const InProgressAddMovieIntentHandler = {
canHandle(handlerInput) {
const request = handlerInput.requestEnvelope.request;
return request.type === 'IntentRequest' &&
request.intent.name === 'AddMovieIntent' &&
request.dialogState !== 'COMPLETED';

.then((data) => {

As far as I understand you are missing the lambda logs in cloudwatch. So for them to enable you need to have an IAM Role with managed polciy AWSLambdaBasicExecutionRole.
That gives following permissions to lambda to log to cloudwatch:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"logs:CreateLogGroup",
"logs:CreateLogStream",
"logs:PutLogEvents"
],
"Resource": "*"
}
]
}
