> in StreamExecutionEnvironment.scala was changed to remove the `returns` call
> starting in version 1.9.0. This causes subsequent transformations on the
> stream to fail since the return TypeInformation isn't set anymore.
>
> Looks like the change was made in [this
> pr|https://github.com/apache/flink/pull/8914]. Guessing it was a mistake
> unless there's some reason to do this that I'm not understanding.
>
> I'm willing to make the PR to fix it, just need it changed so we can start
> upgrading our microservices to 1.9.
