Pipeline not found for AWS integration on Agent managed by Fleet

Using Fleet to manage an agent with the AWS integration. Ingest and indexing is OK, getting tens of millions of logs from Transit Gateway via Cloudwatch, but they are not being processed through the ingest pipeline created during setup of assets for the AWS integration in Fleet. In the agent log, I see this error:

"Filebeat is unable to load the ingest pipelines for the configured modules because the Elasticsearch output is not configured/enabled. If you have already loaded the ingest pipelines or are using Logstash pipelines, you can ignore this warning"

but nothing else looks wrong. No sign of the pipeline failing or being processed at all. I've enabled retaining the original log, it stays as the "message" field. I've tried reinstalling the assets, tried different versions 8.14 and 8.16, tried a local PC and a VM in Azure, tried full agent uninstall/reinstall, created new policy from scratch with only AWS integration, then uninstalled/reinstalled AWS after deleting the policy and recreated policy. Nothing changes the outcome. Tried leaving the output blank, typing "default" and copying the default output to a new one. Same outcome. Any thoughts on what to try next? Anyone got a simple AWS log integration working with a Fleet managed agent? Using Elastic Cloud, so we have no access to the machines other than through the cloud management tools. Documentation has no examples of course. We've raised tickets, but not getting anywhere.

Hello and welcome,

Can you share some screenshot on how this is configured in Fleet, redacting any sensitive information?

Also, share some screenshots on how the logs looks like in discover.

I can't save multiple images as a new user, so here is one big image cap of the Fleet config for the AWS integration. Hope it renders OK. If not, I'll probably have to upload 11 separate messages

Only showing the active elements. All other logs and metrics are disabled, including transit gateway metrics. Those work fine if I do enable them.

also includes Agent status in Fleet and shots of typical TGW logs

Being honest, I don't think that there is an ingest pipeline for Transit Gateway logs, only for metrics.

Is this metrics or logs?

From the documentation, there is no ingest pipeline for logs, only for metrics.

If these are logs then this is expected, you will need to build an ingest pipeline to parser it.
