Visible event source?

Great idea!

I'm having trouble subscribing my Lambda. I can't see the subscription under Event Sources in the Lambda Console, and my logs don't show events being handled.

I used the instructions under "Example: AWS Lambda Function" at https://alestic.com/2015/05/aws-lambda-recurring-schedule/.

But I had to modify them. Initially, I received "A client error (InvalidParameter) occurred when calling the Subscribe operation: Invalid parameter: TopicArn". I think this is because my Lambda is in eu-west-1, but the town clock topic is in us-east-1.

So I issued this command instead:

aws sns subscribe --region us-east-1 --topic-arn "$sns_topic_arn" --protocol lambda --notification-endpoint "$lambda_function_arn"

This command completed successfully.

Should I be seeing the town clock topic in the Lambda Console's Event Sources for the function?

Thanks,

Sheldon.

I misread my CloudWatch logs. *blush*

Explicitly providing the --region flag to the aws sns subscribe command did indeed complete the subscription successfully. It just doesn't show up as an Event Source in the Lambda Console.
