09/02/2022, 11:44 AMSee screenshot - here's the subscribed lambda, as it seems all looks good.
But I have noticed that in the console in the Lambda page, there's no trigger for that Lambda. And when I manually subscribed the Lambda (in the SNS console) the result was an override of this subscription (not a new one) and that also added the trigger in the Lambda. And it all worked well then.

09/02/2022, 3:26 PM@victorious-church-57397 thanks for the tip. I was under the impression that event sources were not for SNS. How do I add SNS as an event source?

09/02/2022, 3:27 PMAh, it might be a lambda permission maybe? I can't see anything there to say sns can invoke it

09/02/2022, 3:31 PM Copy code
new aws.lambda.Permission('sns-event-trigger-permission', {
action: 'lambda:InvokeFunction',
principal: '<http://sns.amazonaws.com|sns.amazonaws.com>',
function: badgerFunc.arn,
sourceArn: topic.arn,
});victorious-church-57397
