I am getting 'occasional' 500 Transport errors on AWS managed ES stack when posting JSONS from our python based lambdas. This was working flawlessly until today's upgrade to ES 7.9. We have tried increasing the cluster sizes as per the AWS best practices. The error goes away for a while and pops up…

Reindex from remote does that for you.

AWS support got back to us. they said its an issue with 7.9 and asked to downgrade to 7.7 by taking a manual snapshot.
So much for being a managed service.
I will update here if that solves the issue
