Thanks for the response. I've created a gist here to demonstrate a minimal repro: https://gist.github.com/egalpin/2d6ad2210cf9f66108ff48a9c7566ebc
It seemed to run fine both on DirectRunner and PortableRunner (embed mode), but Dataflow v2 runner raised an error at runtime seemingly associated with the Shuffle service? I have job IDs and trace links if those are helpful as well. Thanks, Evan On Tue, Sep 7, 2021 at 4:35 PM Robert Bradshaw <rober...@google.com> wrote: > This is not yet supported.
