当KafkaStream尝试反序列化Arvo消息时，我遇到了此错误：
[filtering-app-6adef284-11eb-48f8-8ca0-cde7da5224ab-StreamThread-1] ERROR org.apache.kafka.streams.KafkaStreams - stream-client [filtering-app-6adef284-11eb-48f8-8ca0-cde7da5224ab] All stream threads have died. The instance will be in error state and should be closed.

at org.apache.kafka.streams.processor.internals.RecordQueue.maybeUpdateTimestamp(RecordQueue.java:160)
原因异常是：
Caused by: org.apache.kafka.common.errors.SerializationException: Error deserializing Avro message for id 1
Caused by: java.lang.RuntimeException: java.lang.StringIndexOutOfBoundsException: begin 1, end 0, length 1
at java.base/sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1529)
和
Caused by: java.lang.StringIndexOutOfBoundsException: begin 1, end 0, length 1
at java.base/java.lang.String.checkBoundsBeginEnd(String.java:3319)
at java.base/java.lang.String.substring(String.java:1874)
avro 配置是向前的：
{
"namespace": "io.confluent.developer.avro",
"type": "record",
"name": "Publication",
"fields": [
{"name": "name", "type": "string"},
{"name": "title", "type": "string"}
]
}
这是来自本教程：https://kafka-tutorials.confluent.io/filter-a-stream-of-events/kstreams.html。生产者序列化输入字符串"{"name"： "George R. R. Martin"， "title"： "A Dream of Spring"}"没有问题，但是基本上尝试过滤事件的KafkaStream未能反序列化对象以执行Java过滤逻辑...
以前有人遇到过这个问题吗？感谢任何建议！
发现问题：代理妨碍了。
根本原因是应用无法连接到架构注册表。只需在此处注意，以防以后有人遇到相同的问题。
