undefined method `build' for an instance of Google::Protobuf::DescriptorPool (NoMethodError)

まず lib/gen/dependencies/gogoproto/gogo_pb.rb と、lib/gen/temporal/api/filter/v1/message_pb.rb に至る require パスを調査し、報告されている Ruby と protobuf のセットアップで失敗を再現します。生成された API ファイルが DescriptorPool NoMethodError なしで読み込まれ、影響を受ける依存関係の組み合わせが適切な検証でカバーされれば完了です。

Using 0d3a8bb9037d I get the following error:
