> There seem to be a discrepancy between how Beam Python SDK connects to the
> job endpoint and the artifact endpoint (where it always uses insecure GRPC
> connection), and the expansion service (where it [tries to
> use|https://github.com/apache/beam/blob/master/sdks/python/apache_beam/transforms/external.py#L322]
> local secure channel if available in the GRPC module).
> This has caused an error to be thrown when trying to connect to a remote
> Flink cluster:
