使用DataFlowRunner当光束/数据流意外错误ProtocolMessageEnum未实现

Question

当运行我的梁管道本地所有的工作如预期，但试图在DataflowRunner运行它时，我突然得到下面的错误。老实说，我甚至不知道从哪里开始评估这一点，因为DataflowRunner似乎是一个黑盒子。

检查梁等的版本和升级你的依赖在可能的情况。

我有同样的错误，看到你得到这个错误后，我想这一定是依赖性冲突，因为它之前并不存在。

我使用的是国务院新闻办公室部署到数据流，他们正在使用的只是引用。 https://github.com/spotify/scio/blob/v0.7.1/build.sbt我更新番石榴的protobuf也。

我知道你在使用Java，但尝试更新梁2.9.0，也许番石榴，protobuf的...
