> We have a ES (2.4) database running in production that is not accessible from dev-machines because of VPS firewall rules. However, we do create the Beam graph locally on our machines and submit it to Google Dataflow for execution. However because of this check (line 213)

> the creation of the graph fails because it can't complete the restClient request from our dev machines. This check should probably not happen this early since there is no guarantee that the database is reachable when building the graph
