> I have a Beam workflow that runs fine on Dataflow. However, when I run it on my local direct runner (Windows 10, Python SDK), I run into some strange behaviour if I have a negative number in my PCollection (see below for an example).
> Minimal code example to reproduce the exception:
> {code:java}
> from apache_beam.options.pipeline_options import PipelineOptions
> from apache_beam.pipeline import Pipeline
> import apache_beam
> if __name__ == '__main__':
>     pipeline_options = PipelineOptions()
>     with Pipeline(options=pipeline_options) as p:
>         lines = (
>                 p
>                 | apache_beam.Create([
>                     {"Test": -1}
>                 ]))
>         lines | apache_beam.io.WriteToText('./lines')
> {code}
> Exception:
> {code:java}
>   File "apache_beam\coders\coder_impl.py", line 222, in apache_beam.coders.coder_impl.StreamCoderImpl.decode
