OpenSearch Domain not found

Hi,

We've been trying to forward our ECS application logs to OpenSearch Domain, but unable to do so. We are following official AWS Documentation, but we're getting Domain not found error.

Our task definition looks like this: https://github.com/aws-samples/amazon-ecs-firelens-examples/blob/mainline/examples/fluent-bit/amazon-opensearch/task-definition.json

We're currently using the stable image for fluent-bit.

Any help would be greatly appreciated.

Much thanks!

Start with the linked examples/fluent-bit/amazon-opensearch/task-definition.json and compare its settings with the official AWS documentation. Reproduce the ECS log-forwarding failure and inspect the resulting Domain not found error; the issue provides no additional logs or acceptance criteria, so successful delivery to the OpenSearch domain is the implied completion condition.
