Cloud Operate with AWS Elasticsearch 7.10.2 fails


I’m trying to make an evaluation of Operate, but unfortunately having issues,
getting it up and running with AWS managed Elasticsearch.
It uses v7.10.2.
As I found out, Operation v1.2.5 uses elasticsearch 7.15.0 client.

During startup, this message occurs:
“2021-12-13 14:16:22.627 WARN 8 — [ main] i.c.o.u.RetryOperation : Invalid or missing build flavor [oss]”
The service does not start, because of this.

As a workaround, I took the elasticsearch client sources, patched them and re-packed them back into Operate’s Docker image.

Is there a more clean solution from Camunda available?
