Trying to get CodeBuild to push notifications to an SNS topic (bound to a Lambda), via a CloudWatch Events Rule.
Cloudformation template (see below) deploys fine.
CodeBuild process works fine (have tested).
SNS topic and bound Lambda work fine - I can push a message to the topic via AWS CLI and see Lambda dump that message to Cloudwatch logs.
The Cloudwatch Event Rule seems to be configured fine - I can see it in the cosole, it looks well formed, seems to be bound to SNS topic.
In addition I have been careful to give the Event Rule a role with permissions to sns:Publish, and also defined an AWS::SNS::TopicPolicy for the SNS topic -
Unable to successfully set up SNS on CodeBuild project through CFT but works manually
But still nothing - CodeBuild successfully completes but I don't receive any notifications.
Any thoughts as to what might be wrong ?
TIA :)
