Hi Folks, 

I use that enhanced auto-remediation (https://github.com/PaloAltoNetworks/Prisma-Enhanced-Remediation#getting-started) trying to auto remediate alerts detected in Prisma.
For some reasons some alerts that can not be remediated due to lack of permissions, errors or just deficiency in runbook or any others, constantly trigger associated runbooks in lambda.

I noticed that situation with constantly triggering alert happens when, first time alert is triggered and it can't be fixed due to lack of permissions or just runbook runs correctly but in fact it doesn't fix issue, it triggers lambda(runbook) for some period of time (it looks it is related to parameter Message retention period in SQS) and every 30 minutes (it looks it is related to parameter visibility timeout in SQS ), no matter it is fixed (manually or via improved runbook) or not.

Once alert comes in (first time) and is fixed immediately there are no more triggering as i described as root cause.
I suspect that in second scenario runbook returns something it allows remove that alert from queue. How to handle first scenario ?
