Howdy,
https://serverlessrepo.aws.amazon.com/applications
contains the splunk-dynamodb-stream-processor example, but not the splunk-cloudwatch-logs-processor.
The splunk-cloudwatch-logs-processor shows up in Lambda blueprints, and I don't believe code updates on this repo are making it towards the Lambda blueprint. The way I discovered this is that the blueprint for splunk-cloudwatch-logs-processor had a deprecation warning, and when I sought out how to fix it, stumbled upon this repo and saw the fix was implemented but didn't carry over to the blueprint.
Solution: Kindly add splunk-cloudwatch-logs-processor to the serverless application repo and I believe updates should be carried over.
