无法将 KafkaIO 与 Flink Runner 一起使用

Question

我正在尝试使用 KafkaIO 与 Flink Runner for Beam 版本 2.45.0 一起读取 我看到以下相同的问题：

我有什么遗漏的吗？或者也许一些配置不使用这个 SpilttableParDo？

按以下方式阅读：

PipelineOptions options = PipelineOptionsFactory.create();

options.setRunner(FlinkRunner.class);

Pipeline pipeline = Pipeline.create(options);

pipeline
        // Read from the input Kafka topic
        .apply("Read from Kafka", KafkaIO.<String, String>read()
                .withBootstrapServers("localhost:9092")
                .withTopic("input-topic")
                .withKeyDeserializer(StringDeserializer.class)
                .withValueDeserializer(StringDeserializer.class))
                .apply ....

错误消息表明 Flink 运行器没有用于转换的转换器，这使得 Beam 无法将转换转换为 Flink 可以执行的形式。一个可能的解决方案是使用具有用于转换的转换器的不同运行器，例如数据流

有任何与 pubsubio 面临同样问题的解决方案吗
